Programming language features have their own costs too. Ease of shooting yourself in the foot, how much compile time it take when it scales up to a big project, ease of making tooling, likelihood of making programming mistakes and so on. Add too many features and then your language becomes bad to work with in a large scale because compile and memory speeds explode. Too little and it become bad in other ways.
