I came here to say exactly this. Source: I work in the guts of some of the biggest telecom networks on the planet. Federation is a problem because none of the standards interop. The closest thing we had was XMPP which became mega-bloatware as time went by and is now just not something anyone wants to implement (and it's becoming less of an issue as most of the players move away from open-ness). While the technical among us understand the ramifications of these decisions, the silent majority do not. I believe it was Elad Gil who said that services that eschew privacy have historically dominated their more private opponents. Users say they care about privacy but their explicit value systems (what they say versus what they do) says otherwise. The majority of consumers are happy to take iMessage and use it to the extreme and will attribute silent failures to the operators in most cases (which is not necessarily wrong). True federated identity is the death of the phone network and there are just too many billions of dollars tied up in the world for this to come to pass. A phone number is a ridiculously arbitrary identifier for a person, and yet it works and has worked for quite some time. Logically addressed networks are finally starting to break, and that's a good thing, but the catalyst that will move us away from these systems is one that subsumes existing infrastructure while adding new features. You cannot rip and replace our communications networks (or any infrastructure for that matter) and so the only logical solution is to subsume. It's not easy, but that's how this gets fixed.

It's almost absurd the lack of fanfare surrounding AT&Ts proposed phase out of the PSTN in favor of IP networks. We got number portability and wireless number portability, but the carriers still act as if they own our e.164 addresses and make the transfers arbitrarily difficult. We use phone numbers of SMS, but really we use individual address books, stored in devices, or synchronized with central repositories. We use names to identify people and have to work hard to ensure that our address books are not filled up with duplicates created because we used a one-off email address, or phone number and the phone wasn't able to merge it with an existing contact automatically. We have identity providers that can only represent a small portion of our identity, real names on Facebook and Google+, but cannot resolve that back to our phone numbers or find the best way to contact us at any given time. Presence, which was the real promise of IM and XMPP (and SIMPLE if you must) is not integrated. I cannot determine before hand whether somebody is available to talk on the phone, would prefer a text message, or if I should leave a push voice message they can listen to at their leisure. Even calling a company with a well designed IVR is still a confusing waste of time, when the device I am calling that system from is smart enough to contain any identifier or proof of identity that the called party would need, the protocols are artificially limited to phone numbers as identifiers. There is also no out of band solution to this problem, or the the problem of selecting what department I would prefer to speak with about a problem without navigating a menu that the interface on my device is not really designed to use. Think DTMF on an Android device where the screen shuts off.
