Is there any mechanism in place (other than sending a pr) to capture these
quirks for different devices? I'm used to having to compile different
things to get what I want, but truthfully, I would much rather have it just
work out of the box...
Also, if the quirks are collected then perhaps that will lead to cleaner
handling of devices oddities....
