The optree is read only. So the caller implementation has to respect this.
However, for efficiency it is constructing a scalar which points to the
bytes in the optree. So if anything ignores the readonly flag on the SV it
will be changing the bytes in the optree.

Because the nice thing about your suggestion is that it doesn't involve
changing any of the server infrastructure, and it's an incremental change
which can be done by each mirror in turn.
Instead of running rsync over the whole tree, it can change to run a top
level script that runs rsync over the parts that have to be copied, and then
run the symlink generation on the parts that can be recreated locally.
