You know, really, it would be a "soft" approach to cleaning it up. Imagine the batter going back to the dugout and "telling off" his dumb teammates who just struck him out on a "technicality"!

But really, we could still have the ejection for repeat offenders, but with issuing strikes to the batter for doing it, I doubt it would even get to an ejection.

Of course, would have have to have umpires actually ENFORCE this rule.
