Yeah, I use bezier handles a lot too, it would be imposible to rotoscope without them.
I had just the ilusion to become a miraculous response about it, but you are right, if there were such a technique, it would be all over the place.
Maybe each of us should send a mail to adobe expecting that they create this tool in the next AE version. (Or an aditional rotoscoping plug-in)
