Or move special-topic packages to separate channels, once they get 
implemented. The hard part is of course *where* to split the graph, not 
how to implement it.

I wonder if anyone has analyzed the dependency graphs of software 
packages (not necessarily for Guix, some big distribution like Debian 
would be more interesting), with the goal if identifying good splits 
based on simple criteria.
