if you accept that the library is an improvement over the 6 copies we
have all over the place, the question is only where, not if.
if you insist on making it a separate repository, we'll have a tiny repo
which is an additional dependency of quick1 and declarative, and which
just adds additional burden to any release-related activities.
i wonder who'd benefit from *that*.

that decision is orthogonal to the physical location.
or seen from a different angle, it would be harder to "hide" it if it
was a separate module (well, not really, we did that with qtjsbackend).

but then, i'd totally advocate a git submodule. there would be
complaining how badly this stuff is integrated into the git ui, and we'd
have to make a few adjustments here and there, but overall the solution
is workable.
then i could finally get rid of the three copies of the qmake
evaluator, too ...
