[OSM-talk] area_with_holes as alternative to multipolygon relation

*Then* we'd have to implement a generic system whereby any of the 
outer/inner members can be replaced by relations grouping multiple way 
parts, as you said. But if I were to implement solutions for all the 
hypothetical problems that I can think of, I'd get nowhere...

I didn't want to *abuse* the fact. I wanted to use it cleverly to make 
things easier for people.
