1) It depends of few devs spare time but there are only few issues to fix now (OOTB ready). But remember guys, Daedalus is still experimental ATM.

2) No, of course. Again, just question of spare time to include them.

3) Yes, it should be useful on boot in my opinion.
However, it should be useless for apps: if the device is unresponsive using an app, that simply means the app is to heavy for N900 or SDcard is really too slow.
