"Keli shelishi" is modern coinage, not an actual halachic category.

So the question is whether the list of keli rishon and keli sheini is
because a keli shelishi is too far removed to be worth discussing (RMF,
ROY), or if it is a keli sheini -- all non keli rishon are alike (RSZA).

If we look at irui keli rishon as being an extreme case of keli sheini,
then the MB is taking the latter position as well. Irui keli sheini is
irui into another keli sheini, and therefore it's all keli sheini.

: My question is: where does RMF (and/or ROY) stand on irui k'li sheini?

And if my description of the lomdus is something I remember from a reliable
source (I remember hearing it; can't remember where), they would have to
be meiqil. The MB's chumerah is based on the other sevara.

Tir'u baTov!
