[Feature request] ssh serve backend with --append-only

[vt-alt]

For example borg supports serve command which can be set in ssh's authorized_keys command= and it would restrict that key access to a particular directory including append only mode. Such as command="borg serve --restrict-to-repository=/home/borg/user1 --append-only",restrict ssh-ed25519 ... . This looks like a useful feature if we already have ssh access and alternative to rest server for append mode. What do you think?

With rest server we still have hassle of configuring TLS certificates (or auth is plaintext) and ssh is much more convenient.
