I tend to think that we should favor for former, and only install the base compiler (clang, clang++, support headers and support libraries). If we want to have a "developer mode" that installs everything else, that's fine.

That's a good point; clang-check is (will be) important for users.
diagtool, though, isn't something users should ever need. If a user needs to explore warnings and flags, they should be able to look at some documentation. Installing diagtool doesn't get us out of writing documentation :)
