Nice!  Good to hear that we recalibrate even major processes like this
from time to time.

Yes, I think syncing from testing made for more stable packages, in general.

Perhaps slightly more syncs, but this wasn't a bad thing.  As an
Archive Admin, perhaps slightly more than normal sync requests came
in.  But I think it just showed which packages were more actively
maintained, and which ones people cared about enough to request syncs.

I didn't see much of a difference one way or another.

No information to add.

I think it would be a really good thing for the thousands of packages
from Debian that we sync, without ever touching again (ie, those that
lack an -XubuntuY appendage).  If we're not really actively monitoring
their quality, I think it would be good to sync those from testing,
rather than unstable.  But given that we're in an LTS+1, we can be a
little more liberal about syncing packages specifically from unstable
when requested and when it makes sense.
