Hi Ankit,

obviously there debating about the scope of wayland-protocols, and I
think it is getting to a level where each camp just denies everyone
else's proposal. We need to have a serious discussion of the scope,
remove the extensions that don't belong there, and include those that

But this thread is not for that discussion.

It is always possible to carry a protocol extension in Weston
repository and install it from there, and if it seems appropriate,
promote it to wayland-protocols at any time. The only catch here is
that extensions in Weston need to be namespaced to weston, and the names
will change when moved to wayland-protocols.

Such interface name changes are to be expected even in
wayland-protocols, because they are part of the documented process of
how extensions evolve in wayland-protocols. The final name change
happens when an extension is declared stable, even if there are no
other changes to it.

IOW, there is nothing here that would stop you or Scott from
co-operating and developing the extension and landing it in Weston.
Putting it in Weston saves the politics for later.
