In some respects a minhag can be more chamur than a din. For example: in cases where the reason for the din is not applicable it my not apply whereas if it were a minhag it still would. During a time of shmad R”L one must give up their life for the sake of a minhag.
One reason for this is that the issue of a minhag is one of mesorah. It’s what keeps klall Yisroel going.
Personally, I eat gebrochts. It’s a chumra in oneg yom tov.
Enjoy the rest of the yom tov!
