Well, the problem appears to be that there were so few eligible
conversions that I (and nobody else) bothered actually putting the code
into lily-guile.hh.  Hm.

lily/auto-beam-engraver.cc:    = robust_scm2moment (get_property (this, 
"measurePosition"), Moment (0));
lily/bar-number-engraver.cc:                = robust_scm2moment (get_property 
(this, "measurePosition"), 0);
lily/beam-engraver.cc:      Moment mp (robust_scm2moment (get_property (this, 
"measurePosition"),
lily/beaming-pattern.cc:  base_moment_ = robust_scm2moment (get_property 
(context, "baseMoment"),
lily/beaming-pattern.cc:  measure_length_ = robust_scm2moment (get_property 
(context, "measureLength"),
lily/context.cc:  return robust_scm2moment (get_property (context, 
"measureLength"),
lily/context.cc:  auto m = robust_scm2moment (get_property (context, 
"measurePosition"),
lily/context.cc:  Moment mp = robust_scm2moment (smp, Moment (0));
lily/double-percent-repeat-engraver.cc:      Moment meas_len (robust_scm2moment 
(get_property (this, "measureLength"),
lily/drum-note-performer.cc:                len = robust_scm2moment (scm_call_2 
(f, len.smobbed_copy (),
lily/include/moment.hh:Moment robust_scm2moment (SCM, Moment);
lily/item.cc:        iv[d] = robust_scm2moment (get_property 
(bounds[d]->get_column (), "when"),
lily/moment.cc:robust_scm2moment (SCM m, Moment d)
lily/multi-measure-rest.cc:      Moment mlen = robust_scm2moment (get_property 
(li, "measure-length"),
lily/note-performer.cc:                len = robust_scm2moment (scm_call_2 (f, 
len.smobbed_copy (),
lily/note-performer.cc:        Moment len = robust_scm2moment (scm_call_2 (f, 
available.smobbed_copy (),
lily/page-turn-engraver.cc:  Rational min_turn = robust_scm2moment 
(get_property (this, "minimumPageTurnLength"), Moment (1)).main_part_;
lily/partial-iterator.cc:          auto mp = robust_scm2moment (mp_scm, 0);
lily/partial-iterator.cc:  Moment mp = robust_scm2moment (get_property (timing, 
"measurePosition"), 0);
lily/spacing-options.cc:  Moment shortest_dur = robust_scm2moment (get_property 
(me, "common-shortest-duration"),
lily/time-signature-performer.cc:      Moment base_moment = robust_scm2moment 
(get_property (this, "baseMoment"),
lily/timing-translator.cc:    auto mom = robust_scm2moment (get_property (this, 
"measurePosition"), now);
lily/tuplet-bracket.cc:      auto start_mom = robust_scm2moment (get_property 
(start_col, "when"), 0);
lily/tuplet-bracket.cc:      auto end_mom = robust_scm2moment (get_property 
(end_col, "when"), 0);
lily/tuplet-engraver.cc:      d.length_ = robust_scm2moment (get_property 
(d.event_, "length"),

Hm.  No idea.
