IMHO, haste is broken. But so is, imho, a whole bucketload of spells and magic items. In a campaign where every day has so many encounters under such circumstances that the hasted sorcerer and the machine-gunner... err... hasted archer do not dominate the party, then haste may an ok spell.
I don't play the "average" game. IMC, many things, especially treasure levels, would be broken if I used them right out of the book. I have to check everything before I enter it in may game, to see if it broken, or would break my game, so I don't see any problem with houseruling a spell.
