Yes, it does still resort to setting globals to None. However, the weakref step makes it much more likely that __del__ methods run before that happens. After this change, referencing global variables from __del__ methods is okay.
The first and last sentences seem like a contradiction to me. If I cannot guarantee that globals will be valid when __del__ is executed, then I must not reference globals from __del__.
I think I'm missing something here. Is there some way the programmer can determine that referencing a global variable in __del__ will be 100% safe? (not just "likely")
