The committed change already included an entry in NEWS. Is a "What's New" entry something different?
> I don't understand why there is a PendingDeprecationWarning and not a DeprecationWarning.
Purely because I was following gps' recommendation in the first comment on this issue. Getting rid of PendingDeprecationWarning seems like an orthogonal decision; if it happens, this can trivially be upgraded to DeprecationWarning as part of a removal sweep.
