But do we ever say that the rov is a super strong 60-1 rov? And if it was, you’d expect some discourse on it with R’ Meir who doesn’t hold of rov except in super majority cases.
As per my previous post, this rov has nothing to do with specific numbers, so it wouldn’t be subject to this machlokes.
FTR, AFAIK there are some gedolei haposkim who say like benignuman reported above from R’ Reisman, that the stapling causes a problem, because those treifos are known in advance.
It is a very valid reason to be makpid on CY today even if you hold of R’ Moshe’s heter.
