I thought that they could conceptually make sense in \markup \score
because the score fills the breaking problem by itself, unlike the usual
case where there can be several scores in a book(part) with one breaking
problem for the whole book(part) and thus it wouldn't make sense to set
the breaking algorithm per score. However, it looks like \markup \score
doesn't use the page-breaking variable anyway, Paper_score::calc_breaking ()
runs only line breaking and no page breaking, which makes a lot of sense.
Looking at the Constrained_breaking class, I think just setting
ragged-right = ##t in \rhythm should be OK. Alternatively, if you
feel like it, introduce a variant of Paper_score::get_paper_systems
/ ly:paper-score-paper-systems (the function used by \markup \score)
that does not run Constrained_breaking but just spaces everything
on one line. (It does sound more complicated, although perhaps more
elegant.)

Should I leave it to you to create an issue and MR?


Daniel, as a workaround for the time being, you can use

\version "2.23.11"

#(define-markup-command (rhythm layout props music)
  (ly:music?)
  #:properties ((font-size -2))
  (let* ((mkup
          #{
            \markup \score {
              \new StandaloneRhythmVoice \with {
                \magnifyStaff #(magstep font-size)
              }
              { #music }
              \layout { ragged-right = ##t }
            }
          #})
         (stil (interpret-markup layout props mkup)))
    (ly:stencil-aligned-to stil X LEFT)))


\paper {
  ragged-right = ##f
}

\markup \rhythm { 8 8 }
