Since both products were there for a while, could anyone share some info on this topic?

I did some Google search. Most of the discussions happened before Ventura was released and majority of them are just guessing. Since this feature requires support from both CPU and OS

The only useful info are in a twitter thread (which I am no longer able to find) where a VMWare person mentioned in M2 apple enabled access to some CPU register so could be possible. But no details are given.
