If RMM means the one in the subject line, any argument for why lice have
no mamashus would apply to airborn yeast.

If he means the Brisker approach to tekheiles or orez (as per the
aforementioned Nefesh haRav), it's nothing to do with that topic. Rather,
it's a matter of the legal process being closed. Not a question of what's
right, but of what has the authority to become law. Halakhah can only
come from halakhah.

I think it's of a piece with the contrast between Brisker and Telzher
derakhim. Brisk explains individual dinim in terms of grander halachic
patterns. Halakhah explained in terms of halakhah. Telzh (both subtypes)
will harken back to first principles.
