For now, it is non-keyed. As I mentioned in some other comments I just wanted to get a beta out as I've been rewriting Moon for about a year and it's finally gotten to a semi-usable state.
A keyed implementation, single-file components (multi-file components exist with Moon CLI but I've started to like single-file components), custom DOM events, component inserts, and an official router are on my todo list. Hopefully you'll get to use the library this time :)
