Because sending different content based on the content-type the user-agent asks for, e.g. with the "Accept:" header, has explicitly been part of the HTTP spec since version 1.1 in 1997?

(FWIW - I don't know if that's how `bzr` does this, but it might, and the concept is 25 years old now.)

Edit: s/different content/different representations of the same resource/

True of course, didn't think about that. I'm not a web developer. :) Still think it's weird and kind of against my feeling for the spirit of a URI, but that's just me. Thanks.
