Do you have actual experience with it?
Some time ago I read a comment from someone with impaired eyesight who used an editor that would adjust space indent just fine.
Accessibility is a thing I always consider.
I would have preferred tabs to win for this reason.
Unfortunately, as you pointed out, “good enough” can be excluding, non-inclusive. Overall it works well enough for enough people / none with impairment stumbled over it yet, did not voice or were not heard.
the majority of healthy people has no problem marginalizing minorities with disabilities
I wouldn’t attribute malice like this though. Most people just don’t care or are not mindful and thorough.
