I once posted a snippet for individually coloring ledgers, can't
find it again right now.

Not necessarily: if there were one grob for ledger lines per musical
point, the engraver would most likely still be in Staff, to add
ledgers to all notes from different voices that share them. There
is a hint, however, that there is just one LedgerLineSpanner (per
staff) for the whole score: the very name LedgerLine*Spanner*.
It would be an Item if there were one per musical point.
