I have this edition too, and indeed at #27 the piano and celesta are
reduced to one staff only (with a little brace on the left though,
which LilyPond doesn't handle). But this seems to happen only when
there is too much music too fit on the page: if you look at #97 or
#120, only one hand is playing and however both staves are still
printed.

I agree with you, this should come as a choice. But as both a composer
and a pianist, I *definitely* can't easily find the piano part on an
orchestral score if there are no braces on the left :)

Absolutely. If your sponsorship offer is still good, this is
definitely a feature for which I'm ready to offer a bounty myself.
