Sorry, I don't think I understand the last sentence there but I get  
the sense from the rest of your message that the minimal index will  
not change once released, and new versions of it will be made for each  
"release" (however those are defined in a post-big-release world) and  
that will be beneficial for lots of people.

OK, that's good to hear.

Great.  I'm happy to be wrong.  A mention on the intro page about how  
this versioning scheme is meant to work going forward would be nice.

Nice job,
