Dropping the checks from the parser is a relatively straightforward 
thing to do. My concern would be that some of the basic routines (e.g. 
area calculations) would start to fail if rings weren't closed :(

Yeah, that would be quite useful to have. Is this something that would 
require work on GEOS before the functionality could be added to PostGIS?

There does seem to be a lot of discussion recently about new features; 
perhaps we need to add a "How to sponsor a feature" section to the wiki 
explaining how companies can approach developers to get new features
