Bars, rehearsal marks, time signatures are all isolated events. A
repeat _structures_ its governed material. How could you expect to
transfer a _structure_ to flat music?
How would you expect to have the following R1*9 be expanded into R1*13 ?
\score {
\compressMMRests
\new StaffGroup
<< \new Staff
\repeat volta 3 { R1*2 }
\alternative { { d'1 e'1 } { R1*2 } { R1*3 } }
\new Staff R1*9

}

There is no typeset material repeated in the typesetting either. All
you have is consistent bars. If the bars were to make it into the Midi,
they would likely be consistent as well.

The surprise is rather that repeat bars bleed into parts missing the
specification of repeats in the PDF.
This seems to give false expectations. Maybe we should flag a warning
or error instead.
