Thx for reporting.

Just a FYI: That's not public, it is correctly used in the frame implementation

Just looping in here a little later, working on some improvement for the typing in pandas-stubs and wondering the same question.
At least for 2.3 and 3.0 I don't see it used anywhere. Do we intend to keep it in the code without it having any effect or do we intend to fix it? (Happy to open a PR for it)
