As Robert said, I don't mind removing it.

Briefly, the thing I wanted to clean up is that at the moment we use
Format classes, Format instances, Branch classes and Branch instances
at different places, and this seems a bit redundant.  BranchFormat
instances are generally stateless and more or less factories for
getting Branches, and seem 1:1 with Branch classes, so why not just
fuse them?
