* dput with SFTP provides no progress information
* client support in Ubuntu is recent and the dput.cf defaults to FTP so it's not reasonable to disable it in LP until that's changed, including stable releases
* the dput.cf for SFTP has to have the user's LP name in it, so is hard to have a default at all
* Debian's dput doesn't have SFTP support yet
It's not insurmountable but has both political and technical issues.
