This. It's also easier to strike in without losing position, and Traditional Scarfhold (Hon Kesa Gatame) is a bit of a transitional dead-end and has fewer submissions compared to Broken Scarfhold (my favorite is the reverse triangle from here, both as a submission and a position to isolate and attack the far arm, strikes to the belly (and to the groin on t3h streetz) are very viable from here too). As a pin Traditional Scarfhold is fine and so is useful in Judo and wrestling, but BJJ and MMA fights can't be won with a pin so it's even less useful.
