I am more concerned about code written by admins and users. I kinda
hope that we don't ship too massive shell programs in Fedora, (well,
except of course autoconf scripts...), but I am pretty sure that shell
is one of the most common languages used by admins to do things, and
that's where we should be really careful to not break things.
