If you don’t ever charge it to over 80% then it’s effectively already degraded 20%
I wouldn’t agree. I’m doing that with my car, e.g., or with my notebook. 80% on both never sees the end of a normal day around here, but if I know a day is going to be long, e.g. going to a conference or something like that, I remove the limit before and have 20% more range on the first leg of the trip or know safely that I won’t have to hunt for a plug in the hallway at a party in the evening. If I were to degrade the battery immediately I wouldn’t have that option.
