Upstream has also made a change to have scp use the SFTP protocol by
default. This will appear in OpenSSH 8.8. You can test SFTP protocol
mode now by passing the -s flag to OpenSSH (in main/-CURRENT).

    upstream: Use the SFTP protocol by default. The original scp/rcp

    protocol remains available via the -O flag.

    Note that ~user/ prefixed paths in SFTP mode require a protocol extension
    that was first shipped in OpenSSH 8.7.

    ok deraadt, after baking in snaps for a while without incident
