I tell you what I’m going to do OP, and that’s take all the naysaying, nitpicking and negativity with a very large pinch of salt 
It is what it is. For both GCSE and A level. What we have is not a perfect solution but then neither are exams. None of the students had a choice and they all deserve to either celebrate good results or commiserate disappointing ones, whichever applies to them.
The thing is it is shit for ALL of them.
It is shit for Y11 and y13, who had no chance to prove their “worth” in exams and will now have years of other people sneering and dismissing their results and telling them they never earned them so they’re just “mickey mouse” grades.
It is shit for y10 and y12 who have missed out on huge chunks of teaching and will understandably be nervous about what next year will bring. Particularly shit for y12 given the uncertainty of uni places for next year with all this year’s deferrals.
It is shit for uni students who had their academic year and student lives cut abruptly short and will have to deal with a very different student experience this year.
Shit for younger secondary and primary and nursery pupils in different ways.
It is shit for so many people in so many situations.
What I can’t bear is the attitude of some parents, both on here and in other areas of the media, who are deliberately dissing down and expressing outrage about this year’s exam cohort to big up their own y9/10/12 children and bemoan how much more unfair it is for them. I can’t bear it. By all means express valid concerns but there’s no need to pour outrage and negativity on other children’s results and efforts in doing so.
I am a current y11 parent. I very much hope that significant concessions will be made for next year’s y11 and y13 so that the exam situation becomes as fair as it can be. It may even be that those kids get a much more positive and fair end of school experience than this year’s cohort have. We don’t know yet, but I really hope they do. And you know what? If that happens it will take nothing away from my child’s achievements and I will be delighted for them all.
