I agree with you that we usually do require that we have in-tree users of
new infrastructures.

However, for the download mechanisms, we already have two of them that
have no in-tree users: cvs and scp.

While cvs is a remnant for the days-past, scp is mostly used for
internal resources in enterprise networks. I expect sftp to be used
in the same situation as scp is.

So, I don't see a reason to block it, but as you point out, without an
in-tree user, we can't guarantee the feature will not break. So, I asked
Thomas he sent an updated patch with a test-case.

Regards,
Yann E. MORIN.
