I finally caved and allowed my phone to update itself to 15.2 after it started pestering me repeatedly (even though I thought this was supposed to be gone with iOS 15). Anyway, among the flurry of annoyances and outright bugs introduced with iOS 15, one of the most annoying is my phone constantly asking for my passcode. Literally, every morning when I wake up, my phone will not unlock without me entering entering my passcode - clearly incorrect behavior per the conditions for FaceID and when it requires a passcode. In addition to this daily morning behavior, my phone just randomly does this throughout the day. This isn't followed by repeated FaceID failures or anything else that should trigger the passcode requirement. WHAT THE HELL? I have reported this as a bug to Apple but have received no update on the bug report.
