I have a family member who’s made her career on compliance consulting for the built environment standard for Ontario. She always mentions how much accessibility accommodations are actually improvements to spaces, not just separate “just in case a blind person comes here” utilities. You’re designing for the interface/usage pattern, not so much a specific disability. A curb cut is a usage pattern for anything with wheels. A greyscale mode is a usage pattern for anyone that wants/needs information conveyed without relying on colour distinctions. Tons of those adaptions are just plain useful in cases outside disability.
