The group repos, like hotspot-gc, only accept changes that pass JPRT and
only sync up to hotspot-main after successful bouts of nightly testing.
Your proposed repo would need an equivalent level of testing before
changes could go straight to hotspot-main, so I can only see it working
if it is treated as a child of one of the existing group repos and so we
have:
external repo -> jprt -> group repo [testing] -> jprt -> hotspot-main
But as we have multiple group repos you then need an external repo per
group - which in turn will require a "gatekeeper" from each group to
manage the logistics of the actual jprt submissions and keeping things
in sync.
