Switching to wgpu as the default is a definite possibility, but something should be said for the simplicity of the glow backend. wgpu is a big beast, which takes more time to compile, and for a lot of eframe users it is simply over-kill.
…but then again, if you want simplicity and fast compiles, I can recommend the egui-miniquad backend. It's not as fully-featured as eframe, but with some love it could definitely get there.
Rerun is still in beta, but we think it’s already good enough to be useful. It is built on wgpu, Apache Arrow, my own egui.rs library, and it also runs as Wasm in the browser.
