I expect all the legal teams will necessarily argue that the motions they put forth apply to all LTW holders because unless they do, any trading in DIMEQ by the firms they represent becomes constrained.
What is more, as others have pointed out, in Ch 11 it is unheard of for any class of security to be subdivided for purposes of the settlement (at least without the assent of individual holders, e.g., "assented" bonds whose terms are altered thereby).
The attorneys who object to treating all LTW's pari passu are no doubt just jumping through obligatory hoops in hope that the judge will blink and make some kind of bizarre ruling. Seems to me there are all sorts of motions routinely made for the sake of form in other legal proceedings with no plausible hope of their success.
