I’ll look bl’n.
Interestingly, the C”S, you say, holds you can exaggerate to fight reform, yet doesn’t do so regarding metzitzah.
Yet, the others, who we don’t have any record of allowing exaggeration, are the ones say there are non-medicinal reasons, and you are postulating that they are exaggerating to fight reform.
I really think it’s far-fetched to take it at less than face value.
