Some observations, 1. At this point its extremely hard to use XMPP - there are too many competing standards that implements encryption (of which a subset has forward secrecy), and if sender server doesn't implement any the other end does, usually falls back to plain text, one can disable it - but this is just too much overhead for a regular user. (food for thought [1])

2. Again, reminder from countless HN comments - there is a PR in works to make GCM optional[2], as soon as its merged, this will be solved

3. Maps seems to the real problem here: this could be disabled after 2? (otherwise, whats the point?)
