I suspect keyboard macros have not been used very much in batch mode
over the last 32 years.

AFAICT the current logic of code can be traced back to:

    commit 4588ec205730239596486e8ad4d18d541917199a
    Author: Jim Blandy <jimb@red-bean.com>
    Date:   Wed Jul 3 12:10:07 1991 +0000

    +    error ("Keyboard macro terminated by a command ringing the bell");
    +  else
    +    ring_bell ();
    +  fflush (stdout);
    +}

I'm not sure this code can be said to show clearly that it's not
an oversight.
I read it to say that the author did not consider the intersection of

    noninteractive
and
    !INTERACTIVE
