This gankino horo snip is typeset as (2+2)+(2+1)+(2+2), again not wrong, but scores use the styles 4+3+4 or (2+2)+3+(2+2). (Hitting the same 2+1

What, like this?  I think this is the second bar of the gankino
horo snippet. Here's two ways of doing it, depending on how picky
you want to be.

Yes, both styles exist in my scores. It is though too complicated to wrte stuff i each measure, as in your second example.

I used:
  \tempo 4 = 120
  \time 11/16
  \set beatGrouping = #'(2 2 2 1 2 2)
  \set subdivideBeams = ##t
  #(override-auto-beam-setting '(end * * 11 16) 4 16)
  #(override-auto-beam-setting '(end * * 11 16) 7 16)
Now the beaming, in latest LilyPond 2.11.62, the beaming has changed to:

Changing the above to
  \set beatGrouping = #'(2 2 3 2 2)
does not change this output.

- I think I know essentially what structure is needed to describe these beaming patterns, and even went as far start writing a Haskell program. But the it is a complicated problem.
