How awesome that you take your time to make addons that help folks like that!
I also realize that some well meaning things can be abused by bad actors. Finding a balance between the two is tough.
First, I suggest your friends or associates sign up for the Asscessblity testing. They might get a chance to offer direct input that can help make Blizz games more accessable to all. Info here. Note there is a deadline to submit info.
I do also have a question. Rather than follow, what if WoW had a built in Auto Nav system that can be unlocked like they have in Diablo Immortal?
It has footprints showing you where to go and auto nav that has your char auto follow those footprints to the boss destination. Not useable for botting, but quite useful for mobility or sight impaired folks. Also short term memory issues with finding quest objectives or navigating dungeons. I love it a lot! No more being lost. No need to follow someone else.
It actually addresses some of the issues I brought up here where I talked about a waypoint/footprint system for navigation. (my assumption is the footprint system can have audio ques too).
