Coming at this from a different angle, for \header blocks I often use
multiple 'variables' to get my fonts and sizes just right
title = \markup { \override #'(font-name . "Palatino") \abs-fontsize
#24 "This is My Tune" }
couldn't we do something similar with \tempo in that we simply
('simply'!) have a 'top level' \tempo command and then whatever we
need to specify if it needs a markup and/or a timing?
\tempo { \markup { some value } \bpm {another value} \metronome_mark
{yet another value} }
or something like that ...
Sorry if I have missed a point.
