As others have pointed out, we [the community] need to step up and fill that 
gap.

Here’s something I’ve been using:

\version "2.17"

tsModern =
#(define-music-function
  (parser location dur)
  (ly:duration?)
    #{
      \once \override Staff.TimeSignature #'stencil = #ly:text-interface::print
      \once \override Staff.TimeSignature #'text =
        \markup \override #'(baseline-skip . 0.5) \center-column {
          \number #(number->string (car (ly:duration-factor dur)))
          \note-by-number #(ly:duration-log dur) #(ly:duration-dot-count dur) 
#DOWN }
      \time #(cons (ly:moment-main-numerator (ly:duration-length dur))
          (ly:moment-main-denominator (ly:duration-length dur)))
    #})

theMusic = {
 \tsModern 16.*7 R16.*7 |
 \tsModern 4*3 R4*3 |
 \tsModern 16*12 R4*3 |
 \tsModern 32*5 R32*5 |
}

\score { \theMusic }

Hope this helps!
Kieren.
