We thought about this, we even though about this in the 4.6/4.8
transition. Unfortunately, it might not be a good idea, because even if
you split the lib and keep the old lib around when upgrading the panel
and adding a new lib, the plugins built against the old panel might
still not work with the new panel.

Well, we don't know that in advance. We could force the conflict by
default and remove it if/when we know that the next panel won't have
issues with old plugins though, but that means “transition by default”
which you might not like either. If you prefer that default, then I'm ok
to make the switch
