I'm assuming that you also refer to stable tagged patches that get
"automatically" picked up, right?

We already have a way to do what you suggest: maintainers can choose
not to tag their patches for stable, and have both their subsystem
and/or individual contributions ignored by AUTOSEL. This way they can
send us commits at their convenience.

There is one subsystem that is mostly doing that (XFS).

The other ones are *choosing* not to do that.
