@kimbarrett I provided the basic VM parts here. I'm not aware of what
specifically a GC might optimise if it knows there can be no finalizers, but
that seems like something the GC folk should look to providing as a follow up.
Thanks.

This was intended as an accessor function, similar to `count()` or `offset()`
not a query as-in `is_shared_boot_class()`. As it is a boolean field you could
convert it to a query instead.
