sympathy for naive users, and FOSS devs mainly do not
From what I have seen, KDE devs that I interacted with, had a higher tolerance for mistakes, than I would want to have for myself.
I once submitted a wish for Kate, which was also submitted multiple times before and marked as Won’t Fix, because: a) low demand; b) nobody to do it.
But when I started trying to implement it, I as given more help than I should have asked for.
So, it’s probably just about chance. Don’t let a few rejections stop you. If you consider it useful, even if it gets rejected now, someone will see it eventually. And some programmer might find it worth implementing.
