I would like to note that the goal is to make seamonkey a toolkit app. 
That involves much more than outlined here, and rules out some of the 
approaches (like #ifdefs).

But some of that may be intermediate steps.

We may want to look at catalogs and default stylesheets again, and get 
rid of the "you gotta include xul.css" alltogether, which would enable 
us to just load xpfe.css instead and include toolkits xul.css from there.
