You'd treat them as production platform. I see. But I ask: which
gem versions would you use for developing on MacOS or Debian? And I

But the whole discussion is about development, not deployment. Folks
will start committing Gemfile.lock changes as "bundle install" will be
issued shortly. And we will have this out of control.

I wonder the simplest solution is to provide our own gem repos.
