Code review comment for lp://staging/~alan-griffiths/mir/client-initiates-user-move-and-resize

That's true, but the feature you're talking about in Unity7 also does not have resize handles (right click titlebar and then Resize, or just Alt+F8).

So either the client initiates the resize, and that works perfectly already; or
the server initiates resize, and that works perfectly already too.

Even if you did want it to pop up the resize handles, that's still a shell operation since the window menu itself is part of the shell. Not part of the client.

I think this branch should be just about movement.
