My point is, I think the area is too immature at the moment and needs a lot more innovation before we call for standardization.
Security in particular is an area that often requires breaking away from compatibility (not just in the technical sense, but in the social and network sense as well) to actually work. I worry that we would lose great ideas if we call for standardization too early and stick to the way we do things today, which sucks.
(Also, empirically, fragmentation in other domains, even relatively late in the game, like social networks did not prevent from one clear winner to emerge. I don't see fragmentation as a big issue long term. Perhaps it's even good to some degree for security.)
