For sure.

Well, we currently have (https://lsr.di.unimi.it/LSR/Snippet?id=357)

%%%  SNIPPET BEGINS  %%%
\score {
  \new PianoStaff = "PianoStaff_pf" <<
    \new Staff = "Staff_pfUpper" << \global \upper >>
    \new Dynamics = "Dynamics_pf" \dynamics
    \new Staff = "Staff_pfLower" << \global \lower >>
    \new Dynamics = "pedal" \pedal
  >>
}
%%%  SNIPPET ENDS  %%%

and I think it would be great if [new] users could rather do something like

%%%  SNIPPET BEGINS  %%%
\score {
  \new PianoStaff = "PianoStaff_pf" <<
    \new Staff = "upper" \with { \sendTo dynamic-event "dynamics" } << \global 
\upper >>
    \new PianoDynamics = "dynamics" #(skip-of-length upper)
    \new Staff = "lower" \with { \sendTo dynamic-event "dynamics" \sendTo 
pedal-event "pedal" } << \global \lower >>
    \new PianoPedals = "pedal" #(skip-of-length lower)
  >>
}
%%%  SNIPPET ENDS  %%%

This would mean that dynamics in either the \lower or \upper variables would be 
centred “automagically”, and pedal markings entered in the \lower variable 
would “automagically” appear below the staff — all without having to use extra 
\dynamics and \pedal variables (with all the required skips, etc.). Obviously 
this doesn’t solve 100% of engraving needs… but likely this would cover the 
vast majority of scores most users want to engrave.

Absolutely — that’s kind of why (cf. my email to Valentin) I’m thinking we 
should keep discussing it on-list for at least a little while longer.

Great! Onward and upward.  =)
