I wish I could tell. Judging from
https://wiki.debian.org/Teams/Ruby/Packaging, it seems that
ruby-interpreter requires /usr/bin/ruby. Not sure how official that is.

As soon as /usr/bin/ruby becomes managed by update-alternatives or
dpkg-divert, ruby itself must drop Multi-Arch: allowed, because it no
longer is in exclusive control of /usr/bin/ruby. So this sounds wrong.

I'm not sure we currently support non-default ruby implementations.
Which indicates that jruby should simply drop the provides.

Not speaking with any ruby hats. Maybe Christian can weigh in with more
