Running a perpetual does not allow for weekly time changes.
However, when circumstances mandate, a plant may be moved into the fully dark lung room a week before being ready to trim.

This does not seem to improve yield over having 12/12 the remaining week but is better than trimming a week early.
A lot better.

There is a point to doing that with long flowering narrow leaf. They may never ripen otherwise.

As always it's growers choice. It will speed up ripening but cut back on weight and density during a vital period. Narrow leaf long flowering already built up so much, can't figure it hurts much.

I've suspected as much with the "auto flowers".

That's what I have found as well. It is greatly beneficial to shorten the lights on schedule for stuff that would normally go 12+ weeks, not really much benefit on 8 week stuff (it hurt yields actually). What I wind up doing is running standard 12/12 till I chop the early finishers and then dial it down to 11/13 or so to finish out the rest. I really need to set up another room/area as the sativas do great under 11/13 for the duration of flower.
