Probably great if I had to guess; I've also used Tailwind in a MAUI Blazor app to great effect. The only thing is: there is no DOM for MAUI Blazor components (only HTML & CSS are valid), but since Mud components work for Blazor server okay I'd imagine that wouldn't cause any issues.

Honestly I think this is where Blazor really shines: not in a web app, but as an alternative to the old XAML-based UIs - or even better, an alternative to Electron for desktop app development.
