Sorry to keep replying to myself, but I have some further thoughts.

1. It's probably unrealistic to expect someone to adopt all the GNOME 
components.  If such a person existed, I think we would have heard from him/her 
by now.

2. I'm willing to adopt various components on an as-needed basis.  For example, 
since I want to update gimp and it needs an updated glib2.0, I'm willing to 
adopt the latter and update it to its latest release.  I've just started working 
on it and discovered that it needs an updated gtk-doc, so I'll plan on adopting 
that too.

3. I don't use the GNOME desktop environment, so I am not going to adopt 
packages like gnome-session, gnome-flashback, etc., which I can't easily test.

If no one objects, I'll continue sending ITAs and updating individual GNOME 
components as I need them.
