I thought we were talking about the general question, comparing
various nethods for distinguishing an interactive call.  You seem to
be talking about why some specific function wants to know when it is
called interactively.  But I don't know which function it is.

In general, when a function does something different for an interactive call.
it may be useful for its caller to say, "Treat this call as interactive."

For instance, if `foo' does something special if called interactively,
and `bar' calls `foo', maybe `bar' wants to check for an interactive
call and pass that along to `foo'.  With an argument to distinguish,
that is eas for `foo' to do.  With `callsd-interactiely-p',
it seems impossible.
