I think we want the same thing, you're just expressing it explicitly: 
stgit's usage of the .git namespace should be mentioned in git 
documentation.  actual details belong in stgit, either explicitly in 
documentation or implicitly in the code.

All I'm looking for is a statement like "once we're at 1.0, darcs 
doesn't break until 2.0".  If we don't actually break out a blessed lib 
interface until 1.1,  that's fine with me.  To me, 1.0 implies core 
stability.
