It's not about features or if they work it's about the conceptual load presented to the user by the quality of how those features are integrated, how much configuration they require to do only what you want them to, ask of you only what you want them to, and no more.

When I'm interacting with a maximalist system designed to be everything to everyone, I still only want to have to worry about the things I care about.

They do seem to hold this as a value, but it's secondary to the maximalism.
