Umm, if you replace \break with \pageBreak in my example, you will
see that exactly the same problem exists with page breaks.

\version "2.23.11"

\paper {
  ragged-right = ##t
}

{
  c'1\<
  \pageBreak
  c'1\!
}

\pageBreak

{
  c'1\<
  \pageBreak
  c'2 2\!
}

It's not hard in each case to find some suboptimal value;
you'd need to ensure, however, that an error does not ensue.

I haven't tried it to see if it was hard.

I don't think anyone took it.
