In the same manner as one's freedom-fighter is another's fundamentalist
terrorist, what's flexible could be also dangerous. E.g.,

#!/usr/bin/env python

is forbidden in the core Fedora packages
(https://fedoraproject.org/wiki/Features/SystemPythonExecutablesUseSystemPython),
because nobody is willing to risk that by some random python binary in
/usr/local/bin some core infrastructure of Fedora installations (e.g.,
yum) could be broken.
