No, I don't say I don't want plugins to comply, I say plugins have
nothing to do with complying or not. Plugins' job is to extract tags,
however they achieve that, and correct description is job of whoever is
responsible for writing that into registry. Plugins just don't care what
is written in there.

No, I'm still after distinction between metadata and streaminfo. And of
course one of consequences of that is (potential) writability, and what
follows way of presenting that to the user. But that's side-effect, not
cause.

Yes, where different == reachable independently. Btw, how would you
adjust id3 length w/o having 2 different tags?
