What particular issues are you referring to? You can top-up Oyster with cash at machines and counters. Oyster cards are better as they are ~500ms quicker when tapping ! Cash is still pretty viable in the UK. I can't think of a single place the past decade where they've not taken cash and I've been sad about it or massively inconvenienced - but then again I don't get out much ;) If a restaurant thinks it can get away with just tiny text on a menu informing that it's cashless, you could give them a lesson in the law.
