most of the time spent on homework would be spent with her working out each small component of the problem, eg 5x7, which took hours instead of her knowing the simple times tables instantly so she could apply this instant recall knowledge and focus on the actual more complex problem she had been set.
But as I said in the thread about times tables, some kids are really bad at rote learning. The example you gave my son would calculate 10x7 and halve it, giving 5x7 almost as quickly as the instant recall. Yes, not quite as quick but

he has built much better number sense having learned to do that which serves him well in the college calculus classes he is now taking. Number sense is a meeelion more times important for later maths than rote learning some random math facts. Yes rote learning speeds fluency but so does a calculator.

it works when you have to do 5x27 which rote learning of tables doesn't.
Schools spend so much time with rote learning maths facts that they have less time to spend teaching much much more important early math concepts like conservation of volume and length, place value really teaching it, many primary aged children are weak on place value and it shows up later. Patterns, kids who are strong in higher level maths are really good at spotting patterns. Being able to see in 3D so important for exponents, geometry etc. Being able to visualise numbers and how they work together so that you know your math facts not because you just learned them by heart but you can visualise them in your head and how they work together. Number lines and negative numbers.
IMO schools are way too concerned with teaching kids tricks and memorising to solve puzzles, all well and good while you can remember the trick, sucks if you forget it. If you learn why the trick works, can derive it from start to finish then you can never forget it.
If you truly understand that y3 x y2 = (y x y x y) x (y x y) and you know your fundamental maths rules (associative and commutative properties for multiplication) then you never need to know by heart the first rule of exponents ym x yn=y(m+n) because you can always figure it out. You will learn it through practise but if you haven't done exponents for several years and have forgotten the rule you can always get it back. Not only that but if you really understand why that first rule works you will also understand why ym x z^n can't be simplified. You can easily spot the kids who only learned the rule, they are the ones that try to shoehorn the two different terms into the rule and struggle to understand why it doesn't work.

Number bonds aren't the problem. It's the rigidity of the system that's the problem. Children need to learn methods that suit their learning style but most schools just give them one way to do things and if they don't get it then tough.
I have similar views on phonics (which I teach). Learning to read is a combination of many different skills but so many schools seem to be just concentrating on learning 5 millions different phoneme combinations and all their variations.*
I completely and utterly agree. Some kids are not great learning to read that way. One of my sons learned mostly by inference and context. The other one, well I'm not entirely sure how he learned. He was interested in reading at a very early age so we started working with him a little, naming stickers on everything around the house, reading some very simple primer books with him. However I have no idea how he learned to read "All nude, all of the time" and "Gentleman's club" until he asked me what they meant from the back seat of the car one day! I certainly didn't teach him any of those things!
If you focus your energy on one thing too much something else will suffer.
I guess it comes down to this. Do we want our population to be able to do mental arithmetic or do we want to teach our population to do maths. If all we want is a basic level of maths competency then sure, don't bother with the rest, but if we want our STEM workers to be able to compete against the rest of the world then they need to spend these early crucial years doing something other than just chanting numbers.
