I think it has its uses, but we also have the vast majority of the 
"problem" includes resolved. I didn't remember that these older patches 
were still doing anything other than moving includes.
I'm thinking we need to sit back and do the rebuilding and see where we 
land after I do the include reduction.

  Over the next couple of days I'm planning to submit some 
flattening/re-modulizing patches. so maybe we ought to hold off on this 
for now and maybe then revisit parts of this.  Some of the includes in 
cfgloop.h are impacted and become parts of a backend module header..
