I am not sure what is your point. Does the patch do not solve the
problem? Is it too restrictive? Too complex?

For context: for a log time (at least since Lua 5.2), objects created
by finalizers when closing a state are not themselves finalized (except
through this bug, by calling exit). So, the fact that "we can't create a
new finalizer when closing state" changes nothing, it's how Lua has been
in the last many years.
