It isn't a question of aesthetics, the primary pragmatic issue with languages that have many features is how hard it can be to read a new code base. Tools like macros and traits can save you a lot of typing but when someone else comes into your code, it is much harder to come to terms with it than simpler languages like C or Go where the set of features can all be held in your head and the actual code is explicitly stated rather than generated by macros and generics and such.
This is a natural tradeoff in language design, do you deal with verbosity and boilerplate because the language has few features, or do you deal with the cognitive overhead of understanding all the features?
