Sounds like it would be a cool feature if it existed.  Not sure how
universally useful it would be but it made me think of a similar
feature that I would like.  Similar to above but for structure;

Structure = {
   \key c \major
   \tempo 4 = 110
   \time 4/4
   \partial 4

   % intro
   4 |
   1 1 |

   \repeat volta 2 {
     1 1 1 1 1 1 1 1 1 1 1 1
   }

   1\fermata \bar "|."
}

And then everything else would be forced into that structure.  Perhaps
it can be combined.  Specify the rhythm as you suggest and add a flag
(strict?) to specific parts to apply the rhythm as you suggest.  That
way you don't have to have all or nothing.  Some parts can follow the
strict rhythm and other parts can deviate as long as it fits.

Not sure if key and tempo belong in structure.

Well the second one is possible now.  You can do linebreaks, repeats and, I 
believe articulations as well by simply putting them in a separate definition 
block like this:

structure = {
  s1*4 \break
  \repeat volta 2 { s1*2}
  \alternative {
    { s1 }
  }
  s1
  \bar "|."
}

...and then combining them later with the musical "layer" with something like:


\score{
  \context Staff <<
    \music
    \structure
  >>
}
