Maybe we could reintroduce it; we even have a request from a member of the Debian security team for that (for a different reason): https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=926278 We could also use rubygems-integration itself to prevent `gem update --system`, with a switch to force it if the user really wants it. IIRC the old rubygems package carried a patch doing so (which brought us some flack from time to time, truth be told). > * We (upstream) could maybe detect that a debian package is being updated > through `gem update --system` and show a warning or something.

That is a good strategy in general, and it would be really helpful if you handle things upstream like that in the future.
