Actually, no need for a bug report, as everything here is done in a music
function, and those operate on the input side of things, before we get to
the output side (where the bar checks have no effect).

(At some point this was a big "a-ha!" moment for me when I realized that
music functions and the like are on the input side of things, modifying the
musical input before LilyPond converts it into visual graphics (and/or
midi), while overriding and the like happens on the output side, changing
aspects of graphical items, layout, etc. (e.g. grobs))

Cheers,
