Many if not most of the things on Jeroen's list are things that we'd like to be able to map to calendars.
And the current calendar datamodel sucks for this.
So a root dependency would seem to be "rewrite the calendar datamodel so it is easy to map arbitrary content to calendars".
There have been threads about this elsewhere but it doesn't hurt to make the need for this for dotWRK explicit in your list of dependencies.
