It's the natural thing to do. The modular solver will not even
generate a choice node in the search tree if there aren't any test
stanzas, so an --enable-test constraint will simply have no effect on
such a package. The only other option would be to generate such a node
for every single package, but that'd just make the search tree larger
for no benefit.

Right. I agree. But it should become an independent fix then, right?
