This is especially important when we have so many versions of LiveCode that are current and it is easy to make a mistake and save the stack with a test version. Of course they can't retro-fit version 5 et al, but all the currently in progress versions and any future versions could have this feature.  The message you get could be something along the lines of:

I think you should submit that as a feature request.  It would be very, 
very helpful, not only providing specific useful guidance but also for 
maintaining LC's good reputation with its robust file format.
