Let's not go there. It is not easy at all to know that it used to
exist in the first place, which is more important part than knowing
that it is there and resurrect it. We'd end up hearing from people
that the API is uneven, and seeing a patch that reinvents it, which
we have to review again.
Leaving an unused implementation is not without risk of going it
stale (imagine: when iskip_prefix() learns to honor locale aware
case insensitive comparison, istarts_with() that nobody uses may
be left behind without anybody noticing), so carrying an unused
function is not cost-free, but in this particular case, I think
keeping it is much better economy than removing it, even without
counting the cost of writing this response.
Thanks.
