Err... hack? Justify that statement please.
Few things you might as well address also-
1) update/* runs once per sync; alternatives (building a mapping, or
forcing 2x metadata lookup via hitting up the tree for new metadata)
can't really compete from a amoritized cost standpoint
2) it's simple to maintain; exact atom (rev included), metadata key,
metadata value. Can't realistically rewrite eapi-1 IUSE via it
(default iuse can change the pkgs USE configuration), same for other
build values (CHOST), but it's powerful, and simple.
3) basic infrastructure is already there, so why not reuse it?
