Yes, those might be better names.

I don't see how such a keyboard macro would be useful; can you
explain? If you want to have a way to move to the beginning and end of
the tumme buffer, maybe it's better to add such commands instead? Or
we could do both.

Personally I seldom or never use prefix args for the movement commands
in Emacs, but as they are so many commends that does support it, I
guess people would find such an addition useful.
