The thing is that all interface types behave like this when a network
namespace is removed:
they're destroyed together with the namespace. All which can be
deleted anyway, for which
an `ip link del' command works, - like, physical NICs are the only
exception here b/c you
can't remove a physical NIC from a physical machine this way.
So in this context, wg interfaces are *already* behaving like all
other virtual interfaces,
and this is done by linux network/namespace subsystem, not by wireguard.

Oh dear. It sure makes more sense to me for anything called 'an
interface' to move in the same fashion as any other. Having to 'just
know' which ones will 'remain' and which ones will 'go away and need to
be entirely reconfigured all the time' seems more than the security need
calls for. Just setting the link down when the netns goes away would be
better, I can decide when, whether and how to create and destroy
interfaces. Or at least an option to 'treat all links the same when
the netns goes away' somehow.
Off soap box now!
Thanks for the comments.
