I don’t know. As a neurodivergent person I have been insulted for my entire life for lacking “communication skills” so I’m glad there is something for levelling the playing field.
I can't speak for the OP's experiences, but my early schooling years were marked by receiving a number of marked down or failing grades because my handwriting was awful, it still is, but at the time no matter what I did, I couldn't get my handwriting to stay neat. Writing neatly was too slow for my thoughts, and I'd get lost or go off topic. But writing at a pace to keep up with my thoughts turned my writing into barely understandable runes at best, and incomprehensible scribbles at worst. Even where handwriting wasn't supposed to count, I lost credit because of how bad it was.
At a certain point I was given permission to type all of my work. Even for tested material I was given proctored access to a type writer (and later computer). And my grades improved noticeably. My subjective experiences and enjoyment of my written school work also improved noticeably. Maybe I could have spend more years working on improving my handwriting and getting it to a place where I was just barely adequate enough to stop losing credit for it. Maybe I have lost something "essential" about being human because my handwriting is still so bad I often can't read my own scribblings. But I am infinitely grateful to have lived in a time and place where personal access to typing systems allowed me to be more fairly evaluated on what I had to say, rather than how I could physically write it.
not to get super personal, but that's... not the case for me. i just feel differently about it, that's all!
