Will this implementation continue to work after OpenSSH gets updated on servers? Applications often allow users to pass arbitrary URLs to libcurl. So one can, for example, use scp:// URLs to specify a kickstart for Anaconda. The fact that scp utility will be reimplemented over SFTP does not help much in this case. Each build of libcurl that supports scp:// supports sftp:// as well. But libcurl will not transmit scp:// requests over sftp:// in case SCP is not supported by the remote server any more.
