I had thought of providing a different stash format via
extensions.stashFormat or something instead of this.  The problem becomes
backward compatibility: we essentially can't use stashes with older
versions, and a very common use case in development is to work inside a
Docker container or such where the version of Git is whatever the OS
happened to ship, so such a change can be painful.  It also impedes
working with the repository using libgit2, which is heavily used in some
environments (e.g., the Rust toolchain), until someone ports that change
there.

I'm not opposed to seeing such a format change where refs/stash itself
becomes pushable via a format change, but for my present use case, I
don't want to do that right now.  It's possible that I might write such
a series in the future, or someone else could write it, but I won't be
writing it at the present moment.
