I understand that it's generally good policy to leave positioning of generic windows up to the window manager, but sometimes you want to write a dock or taskbar which anchors itself to screen edges, and can animate in and out of view; or a splash screen which is centered on one screen.  What is the right way to do that on Wayland?

The right way is to have a protocol designed for that. A taskbar
should use some taskbar_protocol with a request like
put_on_edge(edge), and the compositor will then move the surface on
the edge and do slide in/out or whatever effect it wants to.

Not in QtCompositor. Weston has a private protocol to set some surface
as a panel, but it is private and weston-specific.
