wg-quick could be invoked from a network management daemon.  Part of the
brilliance of wireguard is that the in-kernel stuff *doesn't* try to
integrate fancy configuration/setup policy.  But that does mean that
it's likely that there needs to be some user-space policy agent for
system integration.

Please report these suggestions to openresolv or any other resolvconf
implementations.  My point is about what exists today, not about what is
theoretically possible.  This argument will be moot when any widely-used
resolvconf implementation doesn't have to be executed as the superuser
by default.  Please, make it moot! :)

That'd be fine with me, thanks for pushing on it.
