Is this not the practicality / purity discussion from another subthread?
You think it's "less perfect" (by which I think you actually mean "less pure"
 - but please correct me if I'm wrong). But you admit that it's more under-
standable (i.e. it's more practical). Practicality beats purity, so the 
"less pure" solution wins.
