Is the scenario in question that package A2 replaces package A1 and a
new version of package B that used to depend upon A1 now depends upon
A2 such that replacing A1 with A2 would make B in testing
uninstallable even though an upgrade of B would resolve the problem?
(That's a mouthful.) I'd have to think a bit to convince myself that
detecting this in the general case would be computationally infeasible
(though it seems like a distinct possibility that it would be for
large numbers of dependencies), but I can certainly accept that it is
tricky to code and, more importantly, not currently coded, so thanks
for the hint. :-)
