- Google+ has no open RSS output, hence no PuSH support, no write API, in fact it has absolutely nothing open
- Google Reader is scrapped, along with RSS support within Chrome
- WebDav for Google Calendar is dropped in favor of their proprietary API
- XMPP is dropped, while 3 years ago it was at the core of their Wave efforts

If they continue with this trend, then why not drop support for SMTP (and thus email federation)?
