It’s this:
https://gitlab.com/lilypond/lilypond/-/commit/7a09ffee2c69ab9617289afd21dae1b9198a9fee
Perfectly intentional.
Also, reading it in initialize was a bad idea in 2.22 in the first place. That
creates a dependency on the order in which engravers are \consists-ed between
your engraver and Paper_column_engraver. I’ll fix it by doing it in the first
run of process-music. It should have been like that in the first place.
