See https://reproducible-builds.org/ and https://reproducible-builds.org/docs/buy-in/ for why this is a good thing to have in general. Fedora, openSUSE and possibly other Linux distributions package .pyc files as part of their binary rpm packages and they are not trivial to drop [1]. A .pyc header includes the timestamp of the source .py file which creates non-reproducible builds when the .py file is touched during build time (e.g. for a version.py). As of 2017-02-10 in openSUSE Factory this affected 476 packages (such as python-amqp and python3-Twisted). [1] http://lists.opensuse.org/opensuse-packaging/2017-02/msg00086.html
