Should clients use the compose API?

[mahkoh]

Clients might be sandboxed and might therefore not have access to the users compose configuration. Instead of clients using the compose Apis directly, should they instead exclusively rely on the wayland protocols? It would then be up to the compositor to use the compose Apis if no other input method is available.

I think they should: it would ensure an homogeneous UX, reduce start up time and memory usage (I know, modern systems, etc., but a waste is a waste).

This is the direction of Gtk anyway.

Apps supporting both Wayland and X11 would still have to support Compose for X11 though.

It would then be up to the compositor to use the compose Apis if no other input method is available.

It seems fair.
