I am sorry if you feel that there is few reaction on the forum. We try to improve that. If you have a look at https://github.com/alohaeditor/Aloha-Editor/commits/dev/ you will notice that there is a lot of action going on and we are hard working on providing a better user experience with the beloved contenteditable. The probably most painful part of HTML5 spec and browser implementations.
The HTML5 spec unfortunately is very unclear in most cases ("the behavior is UA-dependent" - http://dev.w3.org/html5/spec/Overview.html#user-editing-acti...). Eg. "Break block" is defined with 2 sentences, where we have more than 80 test cases and are far from complete https://github.com/alohaeditor/Aloha-Editor/blob/dev/src/tes...
Though the next release (in a few weeks) should bring a better experience.
PS: mahalo() should work even with the very old stable version 0.9.3. Could you point me to a implementation where it doesn't work?
