For the safety critical stuff, they are probably doing the certification
on the final generated code.

Yes, except maybe those frozen on a specific environment for certification
purposes (which probably were not going to move to x86-64 VMS anyway).

I also suspect a number of other people have reluctantly finally decided
to move away from VMS for various other reasons as well (lack of products,
duration of porting effort, etc).
