Re: How important is comps.xml to us these days? Which packages should be in comps.xml and which not?

You get prompted with the full list when you try and install. You can
use Get Dependencies on the collection if you want to know beforehand.

The hardcoded groups are not lists of packages, it's a map of comps
groups to PK groups.

It's not. Groups are a subset of the comps groups. I've done substantial
user research, and I'm sorry to say fine grained categories _do not
work_ with real users. None of the people in
http://www.packagekit.org/pk-profiles.html could tell me what they
expected to find in base-system/system-tools or base-system/admin-tools,
or tell me the difference between them.

That would be a usability disaster. Do you want to try explaining how a
tristate checkbox works to any of the people on the profiles page?
