Not only does it print 4/4, but it also requires that you specify
\mark \default whenever you change the time signature (maybe this
could be solved with a simple Scheme function though). What would be
really cool is if the Marks were automatically added whenever the
time_fraction changes.

I've been looking (more like staring for hours) at
time-signature-engraver.cc, trying to understand how the grob is
created, but this is waaay beyond my current knowledges.

The only workaround I can imagine would be to use Scheme to override
the \time command, and maybe print the results of
ly:moment-main-denominator and ly:moment-main-numerator to get a
"fake" time signature, but then again I haven't got -yet- the
necessary skills to achieve this.

Noted, thank you.
