The failure mode of a closed carabiner is different and a groove most likely serves only to lessen the ultimate breaking strength of the carabiner.

I don't think that it is a forgone conclusion that a moderately grooved carabiner is weaker than an an ungrooved one. Limited information from BD suggests that the point where the groove develops, the bottom of the carabiner's basket, is not where carabiners typically break in any common failure mode. So moderate weakening there may have no effect on the biner's ultimate strength. Of course, BD presents limited data on a single model of carabiner, so we should be careful about drawing hasty conclusions from it or generalizing it to other models of carabiner.
