A plausible reason would be that it is not trivial to do and nobody
needed it so far.

Lars sounds like he would be better served with looking-at getting an
optional "LITERAL" argument making it do its job without involving the
regexp machinery.

Of course, he could just try something like

(search-forward string (+ (point) (length string)) t)

which should work just fine in his case.  In particular since he appears
to want to move beyond the match (if any) anyhow.
