I don't think that apt should step outside the configured priorities without instruction from the user. Since apt doesn't currently interact with the user (but aptitude does), it can only print an error. That error could be improved with info about alternative solutions to try that are outside the configured priorities, using the -t suite and somepkg/suite syntax. That said, in this case the solution is within the configured priorities so apt could do better.I still miss why a (= x.y) dep cannot by solved in these circumstances.
It would at the very least be a modification to the way apt's solver has "always" worked, as per apt_preferences(5)[1], so one would need to be careful when trying to change it.
