This is a very straightforward extension.
I've been slightly putting this off partly because I have a feeling that
the LilyPond directive code is not in the shape I would wish it. There
are the inserts which are DenemoObjects and then there are the postfix
bits which attach to notes in a DenemoChord. There is some logic to this
- LilyPond treats chords as just "music in parallel" which Denemo
doesn't (and probably shouldn't). But some LilyPond directives (I am
thinking of text markup attached to a note) need additional LilyPond
directives placed before the note (I am thinking of the fine-tuning the
position of such markup). And yet other LilyPond directives are
open/close type things, such as begin/end phrasing slur, and still
others span greater chunks (\repeat or \transpose ...).
I think we can create something that users can understand and manipulate
and which will not (easily) generate bad LilyPond.

Well, no, on the second go you find yourself editing the old one, you
just have to type right arrow (to get rid of the selection) and add the
new text.

the other code is doing. I think there is (or should be) code to handle
a query parameter which causes (d-InsertLilyPond "query") to return the
current LilyPond text. (??? I can't remember whether I did it, or
something slightly different, or just thought it - emailed it?).
