I am astounded by the way you see it.
I did not expect to encounter disagreement on this point.

It seems that you are equally astounded.

I will explain why I see it the way I do.

This is yet one more specific command one needs to remember.  For a
beginner, or even a not-quite-beginner, learning hundreds of other
commands is the hard part.  And it is easy to forget them.

By contrast, what TAB TAB TAB... does inside completion for commands
is a general feature, not similar to any other.

Users will forget commands that they learned, but I think they will
hardly forget this.
