TKND: There are several times in Gemara and Poskim where Chumros are to be avoided because it looks like Kucha V’hitula. (The first one that comes to mind is a Sha’ar Hatziyun that says that one should keep all 5 Inuyim on a minor fast if it’s not a Sha’as Shalom in the world, but to still wear shoes because that looks like a mockery.)
