Yes, that's correct.  It's an ugly optimization that's needed because
lilypond would otherwise be too slow for interactive use.  It will
probably only work (or seem to work) if the changes made are small
enough.  Currently, partial engraving is line-based but we could
even go to measure-based.

My hopes for Schikkers List (if any) are that it would aid in a guile
scheme to sneak the LilyPond dinosaur into the GUI age and thus help
keeping it's relevancy up.

If something like Schikkers List would take-off that could trigger
a real need for partial compilation supported by LilyPond itself.
This is an enormous effort and is not likely to happen any
time soon, giving the overwhelming interest there has been in the
LilyPond community for anything GUI-related.

Greetings, Jan
