I acknowledged in my post that rIntaH and qar'a' are weird examples. (Although in TKD their weirdness is just in where they go in the sentence: the translation of rIntaH as "it continues to be finished" or "it remains accomplished" isn't presented as being in any way unusual.)

But do you have any justification whatsoever for arguing that Do'Ha' and qay'be' are fossilized forms rather than ordinary sentences? Did I miss a memo from Maltz somewhere? (Or are you just mad that your stylistic preference isn't supported by canon?)
