It can be done, but with a little more effort than implied here.
Binding to an interace means wl_registry.bind request, and failing
that
is always a fatal error, which terminates the client connection. All
errors in Wayland are fatal like that.
Instead, the interface should be always bindable, but include explicit
protocol to indicate failure in using its requests.
In this case, we can make something pretty simple, send a signal
to the application if rights to use this interface has been granted.
If the application tries to use the interface without having the rights
to do so, an EPERM signal can be sent (not to be confused with the
revokation signal that happens when .... rights have been revoked).
What do you think?
I would like to have a request_permission and a revoke_permission method
and respectively a permission_granted and a permission_revoked event. An
application might not need to permission or only needs it for a small
amount of time.
Slightly unrelated: We also need a way for a program to ask the
compositor to start a client (and we have to ask ourselves how to handle
arguments, environment variables etc.).
