I can't make the mercurial instructions work; I'm yet to investigate why though.

But my wider point was that there doesn't seem to be a required level of functionality, or even a blanket statement along the lines of "native eol support must offer as much functionality as svn".  eg, what would, and would not, be considered a "deal-breaker" in this area?  Anything?
