The patch below makes it emit

    (setq last-kbd-macro
          (key-parse "A B B A"))

Yes.

If you use the counter or the format, they'll appear as additional
arguments to the `kmacro` constructor.

Thanks, that gives a good reason to support that functionality.

No, the named macros are meant to use the "generic" repetition support,
e.g. by binding them to convenient keys or by using `C-x z`.
