Idk, personally I completely disagree. I don't want to theme every single app. I want them to be distinctive and I don't actually care about native look. What I care about is that they have a nice design (which is as subjective as it gets, I know) but more importantly that they are distinctive enough in terms of design. Now I don't want every app to have different shortcuts or whatever, but I don't want slack to look like discord for example. And I don't want to theme anything ideally.
