user handling, somehow "user-state" is something which may better
parseable in terms of "wg" output - but to implement it in wireguard
itself opens a whole lot of topics. And i prefer solutions build around
the kernel modul itself and keep it quite impossible to trigger an
invalidation of any peer (by manipulating time servers or exploiting
some strange timeissues like leap seconds, timezones etc.) - especially
since this is the special usecase for many2one connections, like your

make the world nicer, please use PGP encryption
