What I found really nice is the possibility to program the input to the 
edition engraver to handle tweaks to the same moment within numerous 
bars. Here's a particularly silly (in so many ways...) example 
illustrating the idea using just some very basic scheme:

\version "2.21.6"

\include "oll-core/package.ily"

\loadPackage edition-engraver

\consistToContexts #edition-engraver Score.Staff.Voice

\addEdition beams

\editionModList beams notes.Voice [ #(map (lambda (n) (cons n '(3/8))) 
(iota 30 1))
\editionModList beams notes.Voice ] #(map (lambda (n) (cons n '(5/8))) 
(iota 30 1))

\new Staff \with {
  \editionID ##f notes
} {
  \repeat unfold 40 {
    \repeat unfold 8 {
      c'8
    }
  }
}
