For implementors it is probably a lot (while it's trivial math usually once resolution etc. is known) But for users: > a handful of folks that can correctly use most of them That doesn't really matter. For most developers a simple guide is enough, the ones with special needs have to know. They don't have to know all either, but different folks with different subsets. Everybody else just has to know "there is more" and read up if they encounter something special.
