Pekak:
I still don’t get it. In the very comment you’re quoting I stated both opinions. If I thought the Chazon Ish was the “only posek” I would have just said it’s assur.
My point was, from my limited understanding, those who asser say it’s vadai assur, those who matir say it’s vadai mutar. I’m not familiar with an opinion that says “it’s a safek so we should go l’chumrah.” What would the safek be here, and who says like that?
