Ah cool so you made it more general to support not just types? Got it.

Yeah, we want to support it on code objects and certain dictionaries (globals, builtins). Option 2a from the linked issue: #124218.

Currently, we only use per-thread reference counting for heap type objects and the naming reflects that. We will extend it to a few additional types in an upcoming change to avoid scaling bottlenecks when creating nested functions.
Rename some of the files and functions in preparation for this change.
