Comment (by 07151129):

 Surely we can "love rust and cargo" without arbitrarily forcing users to
 install it? Many programs that have absolutely nothing to do with GNOME
 (such as ffmpeg) now have this heavyweight dependency, even if otherwise
 they don't need rust at all. Building and installing the old version
 myself defeats the purpose of using the remote ports tree. After all, for
 some ports there are variants for older versions (e.g. ld64); I don't see
 why having an older version fallback would force you to ignore rust.
