I think (and preface most of the rest of this with these two words) the problem is using the word "features"; underneath it all you're just twiddling your infinitely long paper tape, so in that sense no language is more feature-full than any other.

The difference you're trying to highlight is the difference in the abstractions that the language provides that push whatever grunt work/complexity/minutia further out of the programmer's ken and in doing so make their job simpler, and those can be qualitatively compared between languages.
