It's not a protocol issue, someone just needs to write the code.

If someone wants to try this, it's not particularly hard but it needs
to be implemented for the download and upload cases separately. Once
done it would be pretty easy to have it available both for interactive
sftp and command-line scp (when using sftp as a transport).

Also, we don't really do --long-options in OpenSSH, but both GNU and BSD
cp support -i for --interactive, so that should be fine.
