Absolutely right on both points.
I am also absolutely sure that Boeing conducted test flights to check and validate the current MCAS solution also.
I am also aware that, for completely different reasons, they chose to not include it in the "conversion" and line training requirements and crew documentation (until AFTER the Lion Air crash) and thus the "MCAS fault" scenario does not appear in the (few) Level D crew training simulators that are currently in service.
