If it is a מחלוקת, would we say on this ספק דרבנן לקולא?
First you’d need to get to the bottom of it.
See the Pri migadim that the Taz is very shver, as pashtus you don’t need ס״ס there at all. The חידושי הרי״ם is מתמה on the Taz similar to ברכ״י.
Fwiu בית שלמה suggests the Taz is only saying it when it’s anyways mutar מעיקר הדין, כקושית הפרי מגדים.
Main point I’m making is the heter is very questionable. Not saying it’s pashut its assur.
