It notably doesn't use any 'standard' UI framework though, which is frowned upon by some people just as much as using Electron (but for different reasons - usually missing accessibility features and not looking consistent with 'system applications').
I think that's the smoking gun for why most UIs are terrible. it is definitely cheaper to use a framework, but maybe, sometimes, doing something yourself (for 25+) years is worth it
As if there's still a consistent option. It doesn't matter if you use Microsoft, Apple or an OSS desktop: all offer multiple UI toolkit options with varying amounts of consistency, maturity and hardware support.
To bear clear, Blender is not an Electron app (reading my comment again it could be read as such I guess). Blender is a native application sitting directly on the operating system's 3D API and window system (with the UI being rendered through the 3D API, not through operating system widgets).
The WebGL API is sadly two decades behind state-of-the-art for modern rendering, and even the will-be-ready-for-adoption-any-day-now WebGPU spec is ~5 years behind.
Between that and the overhead of running the whole thing in WASM+Javascript, I don't think we'll see a pro-level DCC tool running on the web anytime soon.
