I think it's more than a rumor. As far as I know, Google stopped allowing new XMPP servers to federate, because almost all of the new servers that were trying to were sending spam.
It's possible that they grandfathered you in, if you were already federated when they put on the breaks, and your server wasn't guilty of sending spam.
Or it's possible that I'm wrong and they just got really aggressive about banning new servers if anything even remotely spammy came out of them, and it's really the spammers complaining that "Google won't let anyone new federate."
