Thank you. I see I was involved in the discussion.

The issue is then should the implementer of the module decide if it is 
header-only (i.e. pragma(root)) or the caller (-i).

It would probably be better as the implementer, as a header-only library has to 
be designed for it. It also means the user needn't need to set the switches, he 
can just compile.
