Yeah, I'm actually about -10 to this ;-)

...think about trying to explain why:

context.restrictedTraverse('/plonesite/folder/document').absolute_url()

...works, while the following barfs at you:

tal:attributes="href /plonesite/folder/document/absolue_url"

...which would mean you could no longer use Zope 2's catalog uids as 
paths for traversal, which would be a shame :-/

Then again, I'm +0.1 on dropping empty path elements anywhere but the 
start of the path...
