The first is getting right at the nub of thing. I think accommodations should be made but the worst accommodation is one that would advantage anyone not just a person with a condition that could hold someone back.
So - to switch hypotheticals to one that I was thinking about for no reason - you would give Stephen Hawking a speech synthesizer in Physics 101 not more time. Any student would like more time but no one able to communicate would be interested in a speech synthesizer.
That would be my version of fair in any case. Is it possible? I don't know and the incentives involved would (as I think a lot of people would agree) be pushing towards the worst kind of accommodation.
