Is Pseudonymity a Brand Extension?

The ability to make multiple profiles and isolate them from each other is one of the incredible strengths of the internet. I've always wondered why discord doesn't have this concept of bringing a separate identity to every server, even though it's all wrapped under one log in. And i do think there's this uniting thing that ties together frokin can switch and muse, which is creative tools and helping people. But maybe there is places where that ends being sort of a brand extension.
