I respectfully suggest that we have bins for all of those things

OK, what about "spang" which presently appears in "Q&A About Words". Should that be consigned to the new "Obsolete Words" bin?

And who's going to create all these new bins, and police them, and enforce them?

Are we going to have "poesy" police?

Needless to say, we are going to have a lot more people policing Plutarch's "poesy" than your "obsolete words". :)
