This is exactly what is going to happen but I think it would be unfortunate to 
stall the progress until the new version of the spec materializes. The idea is 
to keep the implementations and the specs in sync, but as Herb has other 
projects too, it takes some time to channel the experience back into the spec. 
As the current version of the warnings found true positives in real world 
projects and we have yet to see any false positives I would prefer to move 
forward to maximize utility.
