They are commands, not functions.  So counting the number of their
calls in the code is not an objective method of estimating their
popularity.

I don't object, although I do wonder what could be the point of
renaming commands which were known under these names for the last
28(!) years.  Given their age, perhaps consider not obsoleting the old
names: who knows whether someone out there has these names burned into
their muscle memory?

Thanks.
