Add a flag or option to the client, e.g. -oSplitExec=true or -E* or whatever. This then uses an execv request type or something like that. If the server does not understand that, this is an error. OpenSSH updates tend to be rolled out very slowly though. So if you wanted any kind of widespread usability of this option, you would've needed to add this about ten years ago. * this is of course alreay taken, it seems only -u and -z are free at this point. You could use -U and pretend to be a roman (EXECUE).
