So I would say that from Gould's opinion, there should indeed be a slope
limit to the tuplet brackets, and that slopes should never be too acute
anyway. Also, it would be great to have some way of forcing the brackets to
be always horizontal, similar to what can be achieved with beams by using
\override Beam.damping = #+inf.0

Cheers,
