to me, it seems *really* pointless to go halfway here. its abundantly
clear what the right design is, so why put a bunch of effort into
cooking up a half-cooked solution that will still need to discarded
for real future?

you guys are working out an incredibly complex and potentially baroque
solution when the elegant and arguably "correct" one has already been
implemented several times in different contexts. what's the point?
