Yes, I think so.

Maybe? I would leave it as follow-up. The change would be local and easy to test separately.
Unfortunately, it would invalidate lots of testing already done for this patch. I can see how much
hassle that would be, and maybe fold that improvement here...

I think so. AFAIU, it caller-saves rscratch1+rmethod, which is what call_VM_leaf_base might expect?
The call is still pretty much there, so calling convention should be kept intact.
