The regular android app constructs its own wgengine with
additional FFI shims, so this default codepath only affects
other handcrafted buids like tsnet, which do not let the
caller customize the innards of wgengine.
Android >=14 forbids the use of netlink sockets, which makes

tell its caller to publish even if there are no ordinary subscribers.

This makes the helpers closer in behavior to cancelable contexts
and taskgroup.Single, and makes the worker code use a more normal

The Client carries both publishers and subscribers for a single
actor. This makes the APIs for publish and subscribe look more
