Yes, I think that's sane. I'm going to be supporting 1.0.x for a
loooong time, so that's something that distros want to ship.

I did wonder about a CdIccDir type object that just had something like
GPtrArray* cd_icc_dir_get_all() and ::removed(CdIcc) and
::added(CdIcc) although I didn't know if parsing each file
unconditionally was what we wanted to do. Certainly if we're doing
basically the same thing in gnome-settings-daemon and xiccd then it
makes sense to share code as it's not exactly trivial.

Right. In a wayland world (using the weston compositor) we want only
the profile side to work, and *not* the xrandr stuff (as it's handled
by the compositor). As part of porting g-s-d to wayland I'll be
splitting the profile/xrandr parts and so I think this is a really
good idea if you do the same.
