A thread like the attendance on focuses on one aspect, and an aspect that people would like changed. One aspect is unlikely to make up the sum total of your child's experience.
I was one of the ones who posted with the worst experience and the worst outcome on that thread. And I do not wish I had kept my dd at home.
The misery that came out of that one aspect was not the sum total of her school career. For a start, it was only one out of the three schools she has attended- the other two were lovely. Also, it did not affect all children in her class and even at that school- most children won't even have known it was a problems.
And even dd, even at that miserable time had hundreds of experiences that were exciting and wonderful and fun and that she will also be able to profit by and remember fondly in years to come: she learnt things, she made friends, she had fun at outings and in the playground, she had good inspiring teachers who made her think about things (maths teacher in Yr 6 springs to mind).
In hindsight I wish I had handled things better, had a clearer idea of what was acceptable (or indeed legal) from a school, been firmer and calmer and called them more quickly on unacceptable practices- and kept my paperwork better.
But I don't wish I had wrapped dd in cotton wool and kept her with me to avoid all possible harm. That would not be the way to teach the resilience needed to cope with life. (HE can be great for other reasons, but not this one).
