REF: move Loc method that belongs on Index
+/- 0 on this; I don't know that this is necessarily clearer as a index method but no major objections @WillAyd gentle ping I don't have a strong enough preference on this to go either way. @pandas-dev/pandas-core for other thoughts if a blocker will have a look soon this isnt a big deal, just a code smell that id like to get out of the way +1: ideally ``if isinstance(labels, ABCMultiIndex):`` should never appear outside ``pandas/core/indexes/multi.py``. Even clearer would be to remove the need for (non-multi) ``Index`` to support this method (but I didn't check how complicated it is - and this PR is certainly good per se). thanks, yeah getting Index/MI closer and closer but there will always be ovrrides. > thanks, yeah getting Index/MI closer and closer but there will always be ovrrides.

Sure! I was just saying that ideally overrides should be only in MI code.
