I'm starting to think No True HNer goes without misidentifying a No True Scotsman fallacy.

They are clearly just saying as you become more proficient with X, Y is less of a problem. Not that if the borrow checker is blocking you that you aren't a real Rust programmer.

Let's say you're trying to get into running. You express that you can't breathe well during the exercise and it's a miserable experience. One of your friends tells you that as an experienced runner they don't encounter that in the same way anymore, and running is thus more enjoyable. Do you start screeching No True Scotsman!! at them? I think not.
