Yellow card for simulation is already a rule. It’s just not applied all that consistently, possibly because it’s very hard to be sure that someone definitely wasn’t fouled and also was deliberately feigning anything, as opposed to genuinely being hurt or at least being knocked over by a nonetheless fair challenge.
Microphoned ref is becoming a thing now, but I absolutely hate it. Just like VAR it slows the game down horrendously and is not needed. Refs have the tools they need to run the game (including hand gestures and red cards, as you said). They don’t need to explain every last thing verbally.
