Right now, some of the establishment ignores B, another considers it a scam and a ponzi only fit for criminals, the third wants to kill it as a deadly competitor, and so on...
It's NOT "required" to follow their ISO.

You think you are going to "get Bitcoin accepted as a mainstream investment in the world's financial markets" by adopting their rules of the systems that B was made to make obsolete?

As the great Casascius saying goes, that would be "a screen-door submarine with a wood trim!"
Bitcoin is an unprecedented entity, that was made to disrupt the old currency system - to be non-conformist, rather than suck up to the establishment.
I think Bitcoin should have the code that it already has, and the establishment should just accept that, or call it whatever they wish, IF they ever actually accept it as a mainstream whatever.
