You are describing how the behavior changes between these versions on
the same repository. That's what I mean by lack of stability.

I'm optimizing for non-experts who never need any refs outside of the
standard set. Now that this version removed the notes ref from the
decoration, the stance for inclusion is simple:

  If Git offers to color the namespace with color.decoration.<slot>,
  then Git decorates with that namespace by default.

This is a nice efficient replacement. Thanks.
