I have in mind to write a wrapper that checks if "newgrp" or "sg" would
succeed and exec itself via that if so. I'm not aware of this being an
existing pattern though.

If we wanted to make it a standard thing, we could provide such a
wrapper in a package and then packages that wanted to use it could
register with (and symlink to) the wrapper.

If working this could maybe fixup the terminal it is running in but not more than that.
- New terminals started from UI might still have old group membership (if not a new login)
- And the UI itself when click-starting things will not have changed

I'm a console guy myself, but that would only only fix part of the problem :-/
Especially as the console-addicted folks are those who would mostly have known "that they have to" and "how to" refresh their groups.
