I think while the use case for runFinalizationOnExit(true) is weird to
begin with, there seems to be a valid reason to enforce the finalizers
to run at the end, e.g. to properly free the *critical* underlying
resources. At this point rFOE(true) trick is, while unsafe, still
operational, right? If we are to remove rFOE(true) escape hatch, what do
we propose users to do?
