Review comment:
There is a `_deprecate_class` in ``pyarrow.util``, but that serves a
different purpose (it aliases the old name to the new class, but with warning).
And if it is just a helper for raising the warning, I am not sure that is
worth it (compared to using a template message that can be filled in).
