Let's compare the two alternatives: .gitmodules versus link object. If I want my fork of .gitmodules, I create a commit on top. If I want my fork of the link object, I create a link object, plus tree object, plus commit object on top of that. But the commit still rebases fine.

On malleability, have you looked at [5/7], where I create edit-link (dead code; half done)? The buffer looks just like a .gitmodules buffer. Fundamentally, what is the difference between this and a blob? git-core can parse it into structured data that it can slurp easily.

I don't want full float or nothing.  I want in-betweens too, and refs are great.
