In any case there were never, and are still not, enough simulators to actually test the MAX properly, so your question is moot. That goes back to the whole issue of timetable pressures.
I don't know how much of this is "news", but rather confirmation of what many suspected months ago. Prolonging the release of information may be justified on legal grounds, but the drip-drip of revelations does nothing to regain confidence.

As claimed by a whistle blower working with the FBI. The single AoA for MCAS to obtain data was intentional move by Boeing. The whistle blower claims that using both AoA vanes would lead to the FAA to require extra training in the simulator. This was not an option for Boeing as the sales was dependant on minor training.
Boeing sold the MAX on it NOT requiring simulator training.
That is the reason there are "not enough" simulators.
Had Boeing used both AoA sensors and the FAA did then decide that MAX did require a similar training event, we would have MANY more simulators than we do today.
Not enough simulators is a direct result of Boeing's words to customers.
Right now Boeing is trying to get everyone including NASA to put pressure on the FAA to say "no simulator training is required" MCAS is good now, even if originally we would have called for simulator training.
In my opinion FAA should throw out the MAX certification and redo it with direct oversight regardless of how long it takes and what training is then decided. Yes it will also hurt airlines around the World but if it looks too good to be true - someone is taking a short cut! and the airlines were/are happy to look away.
