The good news: this is public before any crash...
This did not surprise me. I never expected them to seriously consider a wiring change - not after building more planes for storage than already delivered. ​​​​​So the column cut out in case of MCAS activation must be a software function - that was clear from the wiring diagrams buried somewhere in this thread.
However I think it's a position sensor based deactivation of MCAS - this data should be available from Elevator Feel and/or AP functions.
