I've looked at this before, but I think it's impractically complicated,
unfortunately; britney's not really designed for this kind of
multi-layered check.

Yeah, there's definitely a trade-off here but I would disagree with
Matthias's assessment; I think it's likely to be for the better.  One
way to look at this is that having less noise from build-only packages
should help to reduce the MIR backlog and make it easier to have timely
processing.
