(
'sup dawg, I

herd u like

paragraphs

so I

paragraph'd

this

parENTHESIS.

I'm not totally certain about that.  I mean, I'm not certain that
there aren't some wacky contemporary music pieces that change
this.

Speaking strictly from a user's point of view, why not keep the
  \set beatGrouping = #'(3 3 2)
which automatically takes the denominator of the time signature?
ok, from a code standpoint you want beatGrouping to die, so what
about
  \makeBeamGroupings #'(3 3 2)
and then translate that into the other stuff?  Then simple
beamings (I consider my irregular 8/8 time to be simple :) can
have a simple syntax, while people wanting exact control can do
those nested list funkiness.  In their bases, of course.
