We are not going to change the names, sorry.  Too many Emacs users are
used to these names.

There will be once you invoke the first ispell-* command.

Then I'm sorry, but we will have to agree to disagree on that.

You can always ask.  Like here: you asked and got the answer.

You are again sticking to the name.  The name is not important: I'm
quite sure Emacs was using aspell on your system (if it is installed),
