I thought you were going to write something like this.

1. The report was (supposed to be) about the missing beam over the first 
two quavers, which are not separated by a bar line. So this is not 
covered by the doc excerpt above.
2. If we accept this as a limitation, then it is a severe one IMO. The 
only sensible way to allow mid-bar line breaks is adding a parallel 
track inserting these invisible bar lines in every measure, and if this 
breaks autoBeaming, then there is no way at all. Adding manual beams for 
the entire piece is too much work and completely undesirable.

I’m not speaking about cases like

<<
  { \time 3/4 s4 \bar "" s \bar "" s }
  { 8 8 8 8 8 8 }
>>

yet, where the beam should ideally extend over the whole measure except 
if there is a line break…
