I think this is exactly right, and it is certainly my understanding of White's article: everyone should, and can, find the 'right' position for how he or she wants to ride, taking into account bike type, riding intentions, physical limitations, and so on. It is also true, as you say, that sitting more 'upright' than about 45 degrees or so (torso angle) does compromise (cycling) muscle recruitment. So, the trick is to find one's own 'sweet spot'.
