some fabricated Chumro
Although it’s true that there is a kasya on applying Rabbeinu Tam’s opinion ti certain lattitudes (the G’ra asks it), there were many poskim who did so. In Europe (and even for a short time in the US), some communities kept Rabbeinu Tam even as a kula.
You should refrain from posting your guesses as fact. This is not the first time that you have “fabricated” halachos based on your sevaros, as appealing as they may be.
