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.
