I did not suggest that it should be a "drop-in replacement for
typical `looking-back' calls."

The intention is to have such a function for the quite common,
but special, use case of checking for a literal sequence of
chars just before point.  That is one thing that `looking-back'
is sometimes (too often, mistakenly) used for.

IOW, it's not a case of either-or.  There is a use for
`looking-back' other than the `chars-before' use case.
