That kind of "check-conflicts" would, among others, always
warn on the default build. This would be very irritating and
might do more harm than good.

The general issue here is that it's not about what's being
_built_ but about what's being _used_. We can't reliably
determine this at build time, we can only guess.

In the end, it's always up to the developer. The only things
we can really do is:

a) provide sensible defaults
b) provide good documentation

Static linking always raises some special issues with GPL
licensed software, so I fully agree that we should provide
a summary of all licensing issues that come with static
linking and our design decision for feature completeness.

Yes, that would be going too far.

If two packages (or package versions) can't co-exist, we'll
either have to _make_ them co-exist, or we'll have to make
a decision.
