>> Modern web apps are less about being performant and minimal, and more about dealing with the complexities of large software teams

If that's true, then the app will likely have what I call a "programmer's interface" (which is especially common in most enterprise web apps I encounter). Those apps might be solid from a code perspective, but don't tend to be very user friendly.

I tend to think that modern web apps are more about dealing with the complexities of balancing functionality with ease of use to the end user while still dealing with the complexities of large product teams, which include but are not limited to designers, UX experts and developers.
