I mistyped.  I meant to say that Python file compatibility cannot be fully
determined until byte-compilation time, which happens at installation.  That
is, unless the package has a test suite that runs at build time and fully
touches all .py files.

That doesn't even address correctness against Python 2.7, which is much
harder.  That's one reason why I think all packages should have test suites
and all test suites should be run at build time - *and* the build should fail
if the test suite fails (something I'm not sure happens all the time).
