I'm still not convinced this is a problem; the \voiceXXX commands
are intended for polyphony, so they try to move the rests out of the
way of any other voices.

I consider it a bug too.  The very question is: Why are the rests
under the beam vertically centered even if there is enough vertical
space to move them to upper or lower default position (this is, having
the same vertical position as the quarter rests).

It's a technical issue. Normally, rests  are positioned by

Rest::y_offset_callback (SCM smob)

in the case of beams, positioning is taken over by

Beam::rest_collision_callback (SCM smob, SCM prev_offset)

which doesn't account for #'direction property of a rest. Patches appreciated.
