As someone who doesn’t eat non-gebrokst, I believe that I have a right to call my minhag silly.
If it’s silly, then why do you follow it?
For the record, the Vilna Gaon laughed about the minhag of not eating gebrots, and there are those who opposed this minhag due to not having simchas yom tov.
mw13 – No source, but it’s a davar pashut. Starting from zman issur achilas chametz, one may not eat any food that it is forbidden to eat on Pesach. Kitniyos is forbidden to be eaten on Pesach (for Ashkenazim). Regarding peeling produce – those who follow this chumra (of peeling all produce) are likewise to avoid eating unpeeled produce starting from zman issur achila, although some are lenient due to chametz being botel erev Pesach until shkia.
