Until a feature because quite mature, yes- afterwards, no. That's
the point of keeping it separate.

I've already addressed that, see the messages you reference.

Nope, not the goal.

No, it wouldn't. Because that's not the point.

Yes it is.

Nope, pretty sure that coming in to do a code review at the
end is less time consuming than being involved with a
feature from the beginning.

I like to think that the fact that a patch comes from outside
of core will not impact its consideration by that group.

True, and irrelevant. The sandbox I propose is not the existing
python sandbox. Choose a different term for it if you want,
but anything in it that wants acceptance had better be damned
good, and that, in my mind, includes thorough testing.

Some core devs may decide to use it to produce features that
aren't going to come in under the moratorium, but people outside
the core dev group can also use it. Don't assume that the only
people with the experience and knowledge to implement such
a change are part of the core dev group- especially a couple of
years from now.
