Keeping code in the same repository with a PMC with different sets of
permissions in that repository *is* the sign of a distinct community.
Doesn't matter if you want the code there together, and allowing patches,
and testing and releasing and whatever. Those are technical issues.
Having code with *different* rules for *the same* community members
is not what I know as "community over code" and the Apache way.
And ultimately it's the reason why this email thread won't die. There's
an elephant in the room here (pun intended).
