Yup, that coincides with my understanding.

The files backend could also learn encoding/decoding refnames and
that could be used to transition, if/when we decide to discard the
"refs are organized in a directory-tree like fashion" design we have
been using, to a new world order where a branch M and branches M/A,
M/B, and M/C can co-exist.  Encoding/decoding refname to map to the
filename would also help those on case insensitive filesystems.

Thanks to the recent preparation work for reftable, we are ensuring
that we do not leave direct accesses to $GIT_DIR/refs/* in our
codebase outside the files backend implementation, such a transition
hopefully is getting much easier to do than before.
