Your comment explains why students would like to receive these accommodations (it gives them a competitive edge), but does nothing to explain why this is logical or beneficial.
If as you say the number of available positions is constrained, this system does nothing to increase the supply of those positions. It also does nothing increase the likelihood that those positions are allocated to those with the greatest material need. This is Stanford; I am sure many of the disabled students at Stanford are in the 1%.
Even in the top 1% there’s a limited amount of positions. Everyone wants every advantage possible over everyone else. That is how the market is. Even for Stanford students there is a hierarchy.
Yes, I agree with that, but that still doesn't explain why it would be a good idea to give some students more time on a test. It explains why students would be incentivized to game the system and get more time. But it doesn't explain why we have this strange system to begin with.
Probably started out as an exception for truly difficult situations but like everything else became routinely exploited once widely known about and eventually became a defacto norm and just part of the protocol.
A lot of things start like this. You need someone with an aggressive backbone to enforce things - which these institutions won't have.
