Does this mean the end of custom accessibility controllers?
Xbox has invested extensively in their 1P solution though: https://www.xbox.com/en-US/accessories/controllers/xbox-adap...
It's modular and programmable
I don't have a disability serious enough to need adaptive controllers like this, but I do have RSI, and when I find peripherals that I can use with minimal pain I stick to them. I have to imagine many with more serious disabilities would feel similarly.
