I don't think it needs to be dropped, as it can be useful for
experimentation.  Sometimes, newer rust may be needed and the work to
update the entire collection (with the risks it entails or the build
time) deferred, in which case it could be used.  It's preferable though
to do the work to package the latest and greatest rust and rebuild the
whole collection with it, on a branch though.

I hope that helps,
