Yes it is. A very long-standing API. The fact that you had to go
remove a number of actual uses of the aliases should have told you
this. The documentation is not the API. You cannot remove these
aliases without a deprecation period lasting one full minor release.
2.0 is not license to make backwards-incompatible changes solely for
aesthetic reasons. There is no reason not to follow the standard
deprecation schedule here.

numpy.random was actually replacing multiple libraries at once. The
aliases kind of accreted.
