I don't think we need the extra argument, but need to examine the existing usages. Chances are that any code trying to deal with virtual thread's via the API is actually doing it wrong and will need fixing anyway. I will file a bug.

I think just update the method to use carrier is error prone and callers should explicitly request the functionality.
I'm fine with separate issue, will remove changes in threadSMR.* and restore original handling of virtual thread carrier
