Why android doesn't provide open XMPP implementation?

I implemented asmack in an Android app and it works swimmingly. Communicates well with an openfire server, piggybacks java objects on the XMPP messages to communicate with a game server. No need to depend on first-party support, the protocol doesn't change much.

that topic and most of the comments are from 2008/9

Its still relevant today.

What does it really matter if android ships a XMPP library? Is the barrier to entry to use a 3rd party library seriously that high?

Sure it would be nice if it came standard, but the impression I get from many of these posts is that the believe the sky is falling and XMPP is impossible without google shipping a library.
