I really like that idea because my real case is a 10 page ms with seven 
instruments, for which I need to produce not only a score but various 
combinations of parts; the 2nd idea of adding invisible stuff to the dynamics 
to keep them alive in all systems seems a little unwieldy.

But I’ve run into a problem I don’t understand, illustrated by the following 
snippet:

\version "2.19.23"

PocoAccel = {
     \override TextSpanner.bound-details.left.text = "poco accel." 
}

musicA = \relative c'' {    \repeat unfold 16 c4     }
dynamicsAHigh = \new Dynamics {    s1^AHigh s \PocoAccel s\startTextSpan 
s\stopTextSpan        }
dynamicsALow  = \new Dynamics {    s1^ALow  s\p  s s\f        }
musicB = \relative c'' {    \repeat unfold 16 b4   }
dynamicsBHigh = \new Dynamics {   s1^BHigh s^"espress." s s }
dynamicsBLow =  \new Dynamics {   s1^BLow  s\f s s }

\score {
    \new StaffGroup <<
        \new Staff << \dynamicsAHigh \musicA \dynamicsALow >>
        \new Staff << \dynamicsBHigh \musicB \dynamicsBLow>>
    >>
}

Here I want each musical staff to have two dynamics contexts, one above the 
musical staff for text spanners, etc., and one below for articulations and 
dynamics.  But the above snippet results in both dynamics contexts being placed 
below their musical staff instead of one above and one below.
  
Shouldn’t the line:

        \new Staff << \dynamicsAHigh \musicA \dynamicsALow >>

resullt in the ordering in the score:

        dynamicsAHigh
        musicA
        dynamicsALow

instead of

        musicA
        dynamicsAHigh
        dynamicsALow
?
