Hear, hear! There's a lot of value to having regular place structures. I put a fair amount of work into regularizing the place structures in Old Loglan (an effort that didn't fly), and a lot of semantic categories are very amenable to a "bed of Procrustes" approach. I was disappointed when Lojban drifted off in the direction of custom-crafting each predicate's definition according to which arguments are most important to it. To my mind, every predicate relates a plethora of arguments both through the numbered places and through BAI. Most of these arguments are of very marginal usefulness, and anyone trying to write a computer program to "understand" Lojban or related predicate logic languages would be well advised to not try to represent all of them in the database; however, some of them (like tense) can be very important. I am perfectly willing to have an important argument lack a numbered place if there's a good BAI to stick it on, and the value (for learners) of having regular place structures leads me to be less than generous in welcoming special numbered places for special predicates.
