I am running a previous generation Ultra-torque Record 11-sp crankset with an SRM pm (that I bought 2nd hand) on my 2018 Chorus 11-sp group set. Technically a No No. However, I have no issues with shifts, alignment, etc… Works like a charm. I couldn’t be happier.
Granted, this doesn’t add an iota of insight into the 12-sp world, but @mellowdave did ask about 11S, so here I am.
But all is not lost. For the price of a few 4iii or Stages pms, SRM will hook you up w a 12S Campy Record PM. 1% accuracy candy.
