This is a specialization of "let's form two tribes so we can argue about stuff." "Argue" is not a perjorative here; productive argument is a good thing. We must generally, though treat the other tribe as a customer to aid in making said discussion productive. Perhaps with Web protocols, things are ... entangled in inconvenient ways ( for, you know, ... reasons ) such that the formation of two tribes is a solution. I don't generally build Web things. When I do build a GUI, I intentionally give it an old style, because I'm really a systems programmer ( eek, a third tribe! ) and this invites someone else to express the resulting inevitable disgust in a replacement. But meanwhile, there's an interface for it.
