is OAP used?

Some time back we implemented OAP to add an authentication layer to the IPA,
IIRC aimed at osmo-bsc_nat <-> MAP proxy to do milenage mutual auth.

Now the oap protocol code is in libosmocore, but the oap_client code is dup'ed
in osmo-{bsc,sgsn}.git. I would move the oap_client to libosmocore as well.

But all the while I'm not really certain that it is indeed being used.
osmo-sgsn has vty config for it, but I'm certain osmo-hlr doesn't bother
to implement the OAP server part (there's code but in #if 0).

osmo-bsc_nat remains, and possibly a GSUP counter part to the osmo-sgsn that
I'm not using (presumably the MAP proxy)?

Is anyone using OAP and the oap_client and is it worth the effort to keep it?
Can we / should we just drop OAP instead?

Thanks,

~N
