Chuck suggested ( https://github.com/numpy/numpy/pull/11805#issuecomment-416069436 ) that we may want to consider deprecating np.ediff1d, which is perhaps not much more useful than np.diff, apart from having some arguably strange prepend / append behavior added in.

Thoughts?

Huh. Never knew this existed. I'd say about 50% of the time I use np.diff(), I'm doing that prepend/append behavior manually (and less readably, possibly inefficiently, but most importantly annoyingly).
