@David: We all know that you were a valuable member of the lilypond community for a long time. You were missed, and we are glad that you are back in the pond although we wished you the best for the job you tried. So don't feel too bad for jumping in late.
Currently I have little time as I need to debug my car. Some slack joint or cable break hidden somewhere deep inside the wiring loom or the electronics of the automated gear shift ;-(
Only a few comments: Detecting grace notes by the font size is an ugly hack. I did not know how to detect grace notes in a clean way. Everybody is invited to improve that portion of the code.
Your proposed patch has one problem not found in the original patch: It also adds extenders in addition to hyphens. So we probably also need to listen to LyricHyphen events here.
Also listen_lyric_event() needs to be listen_lyric() for current master.
Attached is a file I use as a test source.

Actually, this is a content vs. presentation issue. The current approach has lyric extenders ‘hardcoded’ within the lyricmode input, whereas often it depends on layout whether I want an extender printed or not:
– In tight horizontal spacing, we might not need an extender, but when spacing is stretched, it might become necessary. This can come through different (page/line) breaking, parallel contexts present only in some editions (part vs. score), Completion_heads_engraver (mensural without barlines/transcription with barlines).
– Long syllables might not need an extender, where short syllables do.
– Often, all voices share the same text, but have extenders in different places. If extenders need not be given explicitly, the lyricmode input code can be reused much easier.
After all, the extenders don’t add any additional meaning, but only serve to improve legibility in such cases where they do.
This would require:
– Recognising the end of a word by absence of a hyphen.
– Comparing printed length of the melisma notes vs. the syllable, likely after line breaking. After all, extenders will never influence horizontal spacing. They might, however, affect vertical spacing. (unless we chose to omit (or shift) the extender in that case?)
– Personally, I think very short extenders shouldn’t be printed. There should be some kind of threshold.
It’s also one of the usecases where a proper representation of a ‘lyric word’ would be helpful, along with issue 2458.
Version 2.12 had this listed as a Known issue.
