You will find Compiz and Openbox people actively participating here, so I would expect your favorite variety of window placement and decoration to appear in due course.

Drag and drop is part of the protocol and is implemented.

As to EWMH not that I know of.  A large part of exposing that sort of information is not yet completely designed (or if it is, those who have done it have not shared the design).  I do not think it is a done deal that the panel/dock is living in the compositor, but that is one possible outcome.

Many of your questions might possibly be answered by a thorough reading of the mailing list and other documentation.  A good fraction of this has been discussed over at least once.
