You can implement your websites with accessibility in mind while also acknowledging its ridiculous how every web developer has to spend time on that because screen readers are terrible, and responsibility somehow got shifted to every web developer ever instead of the handful of companies making screen readers.
I don't loop within loops, I free memory after I allocate it, and I add aria tags to html elements. I don't really see the big deal, just seems like a normal part of the job.
If you just do stuff without reflecting on why it's necessary that's... odd. Two of these examples have actual reasons on why they're necessary, the third is because screenreaders are crap.
I'm not trying to be difficult, but how is it any different than matching what an HTML parser (such as a web browser) expects by making sure you close your tags?
Excellent example because web browsers will render most documents just fine if you don't close your tags. Because they care about being compatible with websites that aren't perfect, and they consider it their job to render all websites that exist. Instead screen readers expect you to change your website instead of working with what's already there.
