The tough part about that is not so much deciding a message, but that it is really computationally expensive to figure out if it has self-intersecting bits or not.

So doing it would probably cause bad side effects, something like everything would stop for 10 seconds each time you did a command, to run the the complex calculations...

One of the big goals of this new properties widget is to try and have a minimal impact on slowing things down, so there are some limits on the types of things that it can calculate so things can keep humming along.
