To me, what makes Han-Wen's plans on World Domination sound quite achievable,
is that if the native output mode is written generic enough, it would be
possible to create a 'liblilypond'. Existing GPLed music notation programs
could use this for their output to the screen. This way, lilypond would not
grow to a beast; main focus could still remain on beautiful music
typesetting, there would only have to be a lib interface as opposed to a
builtin GUI.
I can imagine that in a program like rosegarden, the implementation could be
that when you create a new note, this is first placed on the screen by some
simple & fast drawing routine, without the use of lilypond, and then there
could exists a button somewhere to do a complete redraw (i.e. re-align
everything). But that's just a guess.
