OSMO_DEPRECATED_OUTSIDE vs OSMO_DEPRECATED. […]

yes, we are. On the one hand there is osmo-auc-gen, which is ported in a follow-up patch. Then there is the IPA based OAP (osmo auth protocol), which even has static_assert around sizes of fields in the old sub_auth_data structures. This code is not use by anyone in ages and I have no interest in porting it.

Last, but not least, there are all the authentication related unit tests which use the old API. I actually consider that a good thing, as that way we can be reasonably sure that this changeset doesn't break old users.
