I've found cases of \tempo and \tempoMark at the start of a piece.
The \version was "2.7.40" but I can't recall where I got that
number from. The files are dated 2007-10-30 and were run with 2.8.7
on Debian etch.

But I'm not clear about exactly what the issue is that we're searching
for because it arose out of a conversation rather than one specific point.

How would you deal with the case where \songName landed on a break?
That's the problem I've had to wrestle with in the past. You'd want
the fermata at the end of a line but the song title at the start of
the next.

IIRC in my own first incident of this problem, I wanted two
simultaneous marks at the same barline: a right-justified "D.S. al Coda"
and a left-justified Coda sign, but with the former remaining at the
end of the line if broken at that point, and the latter placed at the
start of the next line. I could get away with anchoring the D.S. to
the last note of the measure.

Cheers,
David.
