“Not sure the point of your question.”
Let me explain then.
. OP suggests we petition the chachamim for more chumras.
. Someone chimed in that chazal have enacted many chumros throughout our history with muktzeh but one example.
. All other examples cited so far, are things enacted by Chazal when they saw a need to do so.
. So I asked. Was there ever a takana (chumra if you wish) exacted by chazal that was done because they were petitioned to do so. Certainly on an individual level people have gone to their Rebbe, Rav etc. and have discussed ways to improve their avodas hashem and were given guidance to take on certain things, but, on the klal level has this ever been done?
