bym: Disagree. There’s no lack of Tznius in explaining Pshat in a Gemara. It’s just not so comfortable in a public setting.
I remember a friend once telling me about a Daf Yomi Shiur he attended. He said that there were a few lines that the Rabbi told them “read the Artscroll, it’s inappropriate to say out loud”. Which is, of course, absurd, arrogant, and ridiculous. If Chazal thought to write it down for us, it’s appropriate to learn.
