I don't believe we need an extra keyword. It could be handled like
start-file-process and process-file: if default-directory matches an
entry in file-name-handler-list, the respective handler is called;
otherwise the native implementation is applied.

It is up to the file name handler to decide, whether a fallback to the
native implementation shall be applied.

This is different to the behavior of call-process and start-process;
callees of make-process must be aware that a process on a remote host
could be started.

Best regards, Michael.
