Re Open Specs:
Assuming specifications are of similar complexity to alternatives, a 
developer should pick specs as they offer an element of future proofing 
to an application. Unfortunately some of the OGC specs don't fall into 
the "similar complexity" category, as evidenced by the level of uptake 
things like the WFS spec.
Encouragingly the OGC has shown signs of recognizing this with their 
recent "Mass Market" focus. So you are likely to find OGC receptive to 
suggestions to simple specs, as evidenced by OGC move toward Simple GML 
and GeoRSS.

If you are looking into routing, I suggest you start by looking at the 
OGC's OpenLS spec. I am not familiar enough with it to make a call on 
whether a simpler protocol would be more appropriate.
