Mike,
If we're going to keep the rule, which is fine with me, the only time it would apply is when the button's first down card is exposed during the deal. Skipping the button on the first card would cause the wrong cards to be dealt to the remaining players, so that would be unacceptable for "proper card." Keep it or bring it back to the way it used to be.
Why does the existing rule call for a misdeal when the dealer exposes the first or second card dealt, yet the third, forth fifth sixth, etc. calls for a continued deal, with the exposed card being replaced by the "burn?"
I also remember dealing hold'em when it wasn't a misdeal if two cards were exposed. They used to replace the first with the burn and the second with the second card from the bottom of the deck. The argument was: it created fits when multiple players had received their "proper card" only to have them taken back for a redeal. Especially a full 10 handed game of Omaha. Your dealing, you expose the fifth card dealt, then you deal another thirty cards and expose another...misdeal...why? Just saying.
