We bumped into this at one point looking to switch our Rust GUI framework and found the best alternatives also suffered a core issue because they both (and almost all Rust GUI frameworks) depended on the same `winit` crate. The `winit` maintainer seemed massively under water.

Honestly, I don't know if open source works outside of a few massive projects any more.
