Then you have even today created something that is very difficult for 
mappers to handle. The thought of downloading the history of one of 
these ways... shudder!

The advanced usage of the multipolygon relation allows you to have as 
many "outer" members as you want (see wiki page), so you can just split 
up your outer way and that's it. It probably isn't perfect in the 
renderers yet but I'm confident it will soon be.

The existing ways will not be touched, but you will be unable to make 
even the tiniest change to a way (you will not be able to change tags or 
add/remove nodes) if the new version of the way would have more than 
2000 nodes.
