Thanks for the discussion and patch!  However, I recently tested a
score with some musicians, and they universally disliked the
"tempo in poet header" hack.  :(   I still like it, but one of the
first rules of HCI (human-computer interaction) is not to argue
with your test subjects, so I'm dropping this idea.


However, what grob produces the tempo mark?  Neither of these
(exaggerated) overrides produces any change.

\version "2.11.61"
\relative c' {
  \override MetronomeMark #'padding = #8
  \override RehearsalMark #'padding = #8
  \tempo "Allegro" 4 = 120
  c1
}
