There are actually 3 dimensions: addressing (the URI syntax), retrieval 
(processing at the HTTP level) and rendering by the UA. As Silvia 
pointed out, the retrieval is not relevant for the spatial dimension. It 
seems that the browser vendors would like to have the rendering of the 
(spatial) fragment within the UA normatively specified. This does not 
mean that the HTML5 will ultimately do that, nor that the Media 
Fragments agree to specify that. See this as an ongoing discussion.

I personally agree that it would be better to have the same URI syntax.
Best regards.
