I have not yet seen a single case where it really makes Wayland less useful. People complain about missing features. These features are missing, because no-one has yet had the time to implement them, not because they are impossible. People are also very stuck with how X does things, since X has been there forever. They attempt to apply the same methods to Wayland, fail, and complain that Wayland is wrong. > Most of us have plain rectangular > screens, and I pretty much like having my applications open up where they > were last, or at the place where I tell them to.

The problems you mention are not related to exposing global coordinate systems to clients. These are just unimplemented features and unspecified protocol. I'm sure they will be implemented, without every application or toolkit reinventing the way to store current position etc. like it is (is it?) on X. That said, if there really are cases where global coordinates are needed to make things work, then yes, I guess they will be exposed. So far that has been limited to very special cases, and I suppose we try hard to keep it that way.
