I would have thought so, too.

I like to enforce extra clearance with 
 \once\override Staff.SustainPedal #'minimum-Y-extent = #'(-3 . 0)
or 
 \once\override NoteHead #'minimum-Y-extent = #'(0 . 3)
before the particular thing that needs more space.

There is also a way to ask LilyPond to ensure horizontal clearance when 
deciding 
how close staves may come vertically:

\layout { \context { 
  \PianoStaff \override VerticalAxisGroup #'skyline-horizontal-padding = #1 
}}
