I think they should at least move the attempt back to the 15 yard line. NFL kickers will still make that 90% of the time but the greater chance for failure makes it more interesting.
They are pretty much a waste of time, they won't be missed after the initial knee jerk outrage.
It's an old holdover from rugby, and I agree that it's a pointless play. The rugby version of the similar play is much tougher to pull off. I would be cool with moving it back, but even then most kickers in the NFL are virtually automatic from short range.
I think it would speed up the game, and effectively wouldn't change the strategy if they opted to go for two.
