I continually run into the problem where I have dynamics wth hairpins
across phrases which cross staves, causing lilypond to throw the
'cross fingers' error repeatedly in a cascade. Despite crossing
fingers (it is a well known fact I dislike this error expression) the
output places the dynamics poorly. If I left these errors in my score
I would have a hundred pages of the cross fingers output in the
compilation log, making it hard to see anything else.

Is this a bug, or is it something fundamental I am doing incorrectly?
The workaround I have to use is to create a new voice for the bars in
question just for the dynamics. This is tedious and clutters the score
unnecessarily. For several reasons I do not want to create a dynamics
context in the score (this may be my mistake?).
MWE follows. [Probably not absolutely minimal, but it shows the
general context I have very often.]
