In my opinion, duplicating functionality under different aliases just
so people can supposedly find things without reading the documentation
is not a viable strategy for building out an API.
My suggestion is to start building out a "How do I ...?" section to
the User's Guide that answers small questions like this. "How do I
iterate over an arbitrary axis of an array?" should be sufficiently
discoverable. This is precisely the kind of problem that documentation
solves better than anything else. This is what we write documentation
for. Let's make use of it before trying something else. If we add such
a section, and still see many people not finding it, then we can
consider adding aliases.
