As you can see in the following not so tiny example inserting the ambitus makes
the \RemoveEmptyStaves command ineffective.
I reduced your example quite a bit and the problem is still there:
\RemoveEmptyStaves does not show any effect in staves containing voices in
which the ambitus engraver is added. AFAICS you are right and this is a bug.
I've modified it a bit further, putting the \consists in a \layout
context. The effect is the same, in that an ambitus prevents a Staff
from beiong considered empty, and this would be Bug 1.
The other effect I've noticed, which certainly seems to be Bug 2, is
that declaring a \new Voice, when Ambitus_engraver is consisted in a
Voice context, causes the ambitus to be engraved at that point in
musical time, wherever it occurs, and not at the start of the staff.
If it occurs at a \break, the ambitus gets engraved *both* at the end
of the previous staff, i.e. before the break, and also at the start of
the new staff. This may be Bug 3, or not: I'm not familiar enough with
ambitus to be sure. We basses just have to know I, IV and V anyway.

}

\layout {

\RemoveEmptyStaves
\override VerticalAxisGroup #'remove-first = ##t
\consists "Ambitus_engraver" % ambitus behaves, but empty staff remains
}
\context {
\Voice
% \consists "Ambitus_engraver" %ambitus and empty staff misbehave
}
}
}
Cheers,
Colin
