Well, that is the sort of thing I was fishing for, but I don't think that's it.
I can find plenty of references that say MCAS only with flaps up, but looks like it is flaps up or down for STS (except on classics?)
-Flaps not up (737-300 & 500).
-Flaps up or down (737-400 & NG).

No definite confirmation of conditions for MAX, but I haven't seen anything that says it is different.
