The only reason it appears in astropy is because of tests that Quantity works correctly with it; we do not actually use it... So that's at least a few hits that do not count as arguments to keep it! I'm in favour of a PendingDeprecationWarning.

We should at least first merge the PR that adds the same padding behavior to np.diff before doing this, then such a warning could say to just use that and get unchanged behavior.
