This comes up from time to time. We are all well aware that MD5 collisions
are easily generated, however, we're not providing MD5 sums as any kind of
warranty. Our use case is simply to say "this is the version of this file
we used to approve the script" - it's a convenience, it is not used for
security. Even if it were, we have no control over upstream sources anyway.
If we hosted sources, which we're not going to do, then we would have used
something stronger.

That said, I'm not against using something else. It's probably not worth
the effort, though, when the end result will be the same. There might also
be something to be said for potentially unmaintained 3rd party tools.
