Are you aware of the options to print a parenthesized bar number at the start
of the line if it's the continuation of a measure? See
input/regression/bar-number-visibility-* (sadly missing documentation at the
moment). I don't have an opinion on whether that is better practice or not than
what you suggest. It is, at any rate, what Gould recommends (Behind Bars p.
490).
Best,
