One can still change the Y-extent in the same way, but the placement
of objects no longer uses the Y-extent, if LilyPond is able to get an
outline of the object (the outline being called a skyline).

The announcement of the change is at
http://lilypond.org/doc/v2.17/Documentation/changes/index.html
after "LilyPond no longer treats objects as rectangles" 
and the "Previously" image links to sample input showing how to
get the old behavior.

\override Score.VoltaBracket #'vertical-skylines = #'()

Maybe we would benefit from an announcement of the change that
makes more clear its implications on spacing overrides...
