If you start with optimized code from the AOT compiler, and do sampling based profiling every so often, the overhead is miniscule The only time it would probably be a net lose is when you have a very large number of short lived executions.

Okay, and if you manage to show that it's feasible in practice, I am sure people would adopt such an approach.

Err, people already do it, but you are probably not going to see widespread adoption anytime soon no matter what. Until nobody has to think about it, nothing changes
