Recording cherry-picks in your workflow certainly makes sense, but I'm
not talking about workflow-level issues here. You are adding an extra
header to the commit object. I'm talking about the object database and
low-level Git model implications this has.

In other way, I think this is purely a porcelain matter and recording
this information in the free-form area is more than enough.

Why?

And why are the notes created by git cherry-pick -x insufficient for that?
