Or rather 1.20 I guess https://github.com/numpy/numpy/pull/15900.

By the way, it would be useful if deprecation warnings like this had a
functionality to enable the actual post-deprecation behavior. Right
now the warning says to run warnings.simplefilter('error'), but this
causes the above indexing to raise DeprecationWarning, not IndexError.
