That would depend on the terms of reference.
If the question is a closed one, such as 'do you prefer airline or table seating' then of course compartments will not be mentioned.
If the question is open, such as 'what sort of seating layout do you prefer on a train'? or provides the full range of options (airline, facing with table, facing without table transverse or compartment) then the responses may be different.
Can anyone point to any research that supports one side or the other in this debate? So far we have all (me included) had to rely on subjective arguments, personal preferences and bare assertions as to what we THINK the travelling public might want.
And then every "want" has to be tempered with cold hard reality. Personal safety will edit out compartments before they get to a short list to chose from. (see Public Sector Equality Duty).
Compartment would also necessitate a vast increase in CCTV camera to meet coverage levels.
As reminder the rolling stock in mainland europe is almost exactly a foot wider at the widest point and far wider at floor level than the UK hence what might make sense over there can be very space in efficient over here as you effectively lose a seat.
