Indeed... magical hand-wavey part is the only teeny-tiny flaw with my
proposal that the problem be magically, hand-wavically solved --
otherwise, it's rock-solid :)

OTOH when you're spending ten hours a week waiting for revdep-rebuild,
preserved-rebuild stops seeming like an intractable fantasy and more
like an interesting puzzle you'd might as well take a crack at
solving.

I dunno about y'all but my not-really-that-computationally-powerful
workstation has 2000 packages installed, about three-quarters of which
seem to have forked webkit (just kidding, but it sure feels that way).

emerge -e @world literally takes me two days if I'm lucky.  If I'm
not, more like a week, with my cores left mostly idling while my
productivity is thwarted by various non-webkit-compiling distractions
like using the toilet or working.

Point being, it's damn slow; I'm starting to feel like the guy waiting
for revdep-rebuild all week.  There's gotta be a way to do it.  If it
requires some encapsulation-breaking hacks to get it done (as
preserved-rebuild kinda did) it's probably well worth it.
