Yes, it is true that for a stereo only system, you can load the rear samples to add a bit more acoustics. Such mixing is actually becoming quite common in recent sample sets.
In the case of Rotterdam I think the front samples have a very good balance between detail and acoustics already. I just did a quick test on my set up. Adding the rear samples to my front speakers resulted in a small change compared to muting the rear samples completely: it added a bit more acoustics, but, judged subjectively, at a small cost in clarity and transparancy of the sound. (When testing without rear samples, I increased the volume of the front samples by about 2 db to compensate for the volume increase when you send front and rear through the same speakers)
If, due to RAM limitations, my choice were between muting the rear samples or muting ~20 stops, I would choose to let all the stops speak!
