For the final stable protocol, yes.

During protocol development though, we could add a bit of extra and ugly
protocol to create experimental add-on intefaces to e.g. wl_seat. This
would be similar to how you plug wl_viewport to wl_surface (scaler.xml).

When the protocol finally gets stabilized, the experimental global
interface will be removed, and the changes to the protocol and code are
hopefully purely mechanical and fairly easy to review.

Can you see that working?

It is a heavy-weight method, so probably not useful for easy additions.
