XAML is good. It's very easy to build interface by nesting components then styling it if needed, and doing data binding. All the web alternatives are harder to use and came 10-20 years later.
React, Vue, Svelte as well as Flutter & SwiftUI all implement different but vastly more productive reactive dev models.
MAUI will not be resurrecting .NET Desktop Apps which have been on decline since WPF. Blazor Desktop Apps might, anything XAML won’t.
For example, my experience with CSS has been the opposite of that. F5 a million times before the layout works the way I want it to. Sometimes even googling how to do create some type of layout because I can't think of it on my own.
