The initiation of the problem caused by the single point of failure of only using one AoA vane has also been removed by the MCAS being linked to both AoA vanes. In other words the direct MCAS threat has been removed.
So your post should really use the past tense.
We haven‘t seen the updated version life, have you? Just vapour ware. Can‘t see why past tense should be mandatory.
