That would create a dependency on tar binaries or require a reimplementation.
Rewriting scp to just use sftp seems to be the easier option, even if it's not as efficient. Efficient is rsync's domain.
Getting something done without too much hassle and easily chroot-able would be scp/sftp.

Actually sftp is more efficient than scp, too. scp has its own awful buffering on top of TCP (lots of HPC sites used a patched version to avoid speed limits). Or at least did 10+ years ago when I checked; it's possible that OpenSSH has managed to circumvent the issue now.

IIRC SFTP is more like NFS than FTP and latency limits its bandwidth quite a lot.

SFTP server is not available everywhere either (in embedded systems especially).
