Right, as long as the reverse dependencies use the := "SLOT operator"
like they're supposed to. That's how they let the package manager know
that they'll need to be rebuilt when the ABI changes.

Yeah, blockers are already used like this sometimes, like for
google-chrome which has mutually exclusive stable, beta, and unstable SLOTs.

Well, we can always introduce a separate ABI_SLOT variable in a later
EAPI, if we want.
