That depends on the perspective ... (RFC 2732 Grammar vs. Prose)

And if you give precedence to the formal grammar change this is not a 
normative change because there has been a change form the RFC2732 
grammar to the RFC 3986 grammar again dissallowing the re-allowed square 
brackets in the fragment.

So, also not to include square brackets can be seen as a normative 
change depending on wheter you give precedence to the the grammar or the 
prose of RFC2732.

My feeling was that it is less drastic for people to escape (or accept) 
square brackets in the fragment than to dissallow existing "street" 

So please reconsider this, althogh you can see from my original posting 
(Martin, you intended to repost this here but I haven seen it yet) that 
I do respect both positions.
