A serious problem with not shipping precompiled pyc and/or pyo files is that,
once generated on first run, package managers won't uninstall them.

This can cause many undesired effects, because python programs will still be
able to import these files, but dependencies like graphics or shared libraries
may have been deleted by the package manager.

Also, not being able to uninstall something is bad on its own.

So, if anything, I believe INCLUDE_PYCS = "1" would be the only sane default,
unless no package management was involved at all.

And no read-only filesystem, for what it's worth.

Best regards,
Andreas

P.S.: I didn't see patches 2 and 3. Is it just an incorrect subject?
