I working on a project using tauri with htmx. I know a bit uncommon. But the backend part use axum and htmx. No Js/Ts UI. It's fast, reliable and it work well. Plus its easy to share/reuse the lib with the server/web.
Even if its cumbersome, it's still a win-win for them to use it.
The outlook app will be native desktop and mobile (except linux for now).
Plus it will give the maui project more credibility, help grow its userbase. Make the framework better by providing a real world project for the maui team to benchmark, highlighting pain point, provide in-house feedback, feature request.
You must break down the part that led to that reputation.
Electron uses its own renderer (chrome). Meaning it can't share memory with the os browser and make download size way bigger.
It bundles nodejs. Again make download size bigger
Nodejs needs to create multiple processes which each of them can use a lot of memory.
It use a bridge between the UI and backend (to do os stuff)
while JS is nowaday fast, Go/Java/C#/etc are still faster
Wails on the other hand.
Uses the os browser. (Download size is reduce and can share memory)
Go is compiled to native, no runtime needed. (Download size is reduce, lower on memory, run faster)
Same bridge performance bottleneck, but you can perform critical stuff in Go and get an advantage.
HTML renderers are fast. Code your UI with performance in mind, use a library like svelte or solidjs combine with something like wails (or anything that will do the same thing in java/c#/swift) and you won't see a difference between any native apps in most cases.
Also you gain the ability to share your UI code with the web.
