Deprecating SCP

Hi Fedora users! Over the last years, there were several issues in the SCP protocol, which lead us into discussions if we can get rid of it in upstream [1]. Most of the voices there said that they use SCP mostly for simple ad-hoc copy and because sftp utility does not provide simple interface to copy one or couple of files back and forth and because of people are just used to write scp rather than sftp. Some months ago, I wrote a patch [2] for scp to use SFTP internally (with possibility to change it back using -M scp) and ran it through some successful testing. The general feedback from upstream was also quite positive so I would like to hear also opinions from our users. It still has some limitations (missing -3 support, it will not work if the server does not run sftp subsystem, ...), but it should be good enough for most common use cases. Today, I set up a copr repository with the current openssh from Fedora + the patch [2] for anyone to test and provide feedback, either here on the mailing list, or in the github PR according to ones preferences. I am looking for any kind of feedback from the idea through the usability, implementation. Is this something you would like to see in Fedora soon? Do you have something against this? Is your use case missing?
