Um.  Well, reduction of geospatial polygons, either in a smoothing  
mode or (more likely for alerts) in an "enveloping" mode, is  
certainly a fact of life.

Still, I'm having difficulty with the idea that we would adopt a  
format that roughly doubles the byte-size of each polygon, and then  
ask senders to reduce the resolution of their data to compensate.   
Seems like that might be a triumph of form over function, doesn't it?

Anyway, I'm not sure anyone is actually having a problem with the  
existing polygon format, so are we in danger of trying to fix  
something that isn't really broken?
