Can someone explain why this is a protocol problem?  If there’s a
client-side workaround, why isn’t the filename escaped in the scp

This is a potentially nasty security problem for a trusted script that
scps files from a remote machine, because a malicious filename
containing `` could cause arbitrary code to be executed remotely.

A similar problem exists with the ssh client:

$ touch "123 456" 789; ls
123 456
$ ssh host touch "123 456" 789; ssh host ls
