The problem is that believing that scale x*3 does something different than
it really does gives you an artificial barrier to overcome later, when you
discover that that's not really what it does.

Personally, I think the current behavior is perfect: it allows you to use
scale x*3 as if it works that way, but it reminds you each time you do that
that's not really what it's doing and we're just letting you get away with
it.
