yes, but in 20 years nobody has gotten around to it. :)

I don't think many people want *complete* feature parity, and that's 
probably impossible to do without reintroducing the same security issues 
as scp. What would make sftp a viable replacement is simply supporting 
sending and receiving files with optional permission preservation and 
recursion (99.9% of what scp is used for). sftp is most of the way 
there, but if someone can't send a file with a simple sftp invocation 
they'll just keep using scp.
