These are all real questions which we should tackle.
It's depressing that we've been asking them for years, without coming
up with anything but "collaboration is too complicated", even between
ASF projects.  Even more frustrating is that AFAIK, the "Commons"
project was originally started to do just that!  For a long time, we've been
totally open to committers from other ASF projects; yet no synergy has
ever emerged (as far as I remember correctly).

I hope that it will be different this time.  [Thank you, Johann, for reaching
out.]
