I did hunt-and-peck for about a decade of my career. Then I realized that I was often sitting there staring at my keyboard, not at the output on my screen, so I'd have to then go back and find my cursor and probably fix some errors (again looking at the keyboard). So I sat down and taught myself to touch type. And then I could touch type. And then it wasn't a problem any longer.
Something that isn't clear in this anecdote is that for those ten years, I wasn't employed, I earned my keep doing software development independently, and I started that while I was still in college. I didn't ask someone's permission on whether to write code without touch typing, I just went and did it, and since I was paying the bills, nobody cared. Can someone make a living as a software developer without knowing how to touch-type? Sure! But if you aren't going to bother to learn a skill that is obviously useful in your field, then you'll need to have compensating skills elsewhere, which is to say that someone who can't be bothered to learn to touch-type most likely doesn't have those compensating skills to fall back on.
Like, seriously, this is a trivial thing litearally anyone can do to make themselves more employable. Who even cares about quantizing how useful it would be? For sure some people can't learn to touch type, like literally, because of neural wiring or other issues. But, unfortunately, NOBODY CARES, that's a you problem. If you're in that position, you'll need to invest time in compensating elsewhere for the fact that you can't equip the touch-typing skill. It will probably involve a lot more work than it would take the average person to learn to touch type.
People honestly have no idea how much harm it does to their career when the most basic project turns into a subquest. People gain stature not by being ABLE to do things, but by having a faster cycle time. Remove barriers rather than preserving them. Quit asking for the parameters of your accomodations and just learn your shit!
