I’d doubt this will really work for more than Rust or Go (maybe C#) with their heavy static linking and single-file native binaries. Given how hard sharing native libraries or runtimes between wheels is (that reason why Conda exists), wheels aren’t going to solve distribution of arbitrary software. I’m somewhat surprised that even CMake fits in a wheel.
If Go/Rust users want a free-access repository with a flat namespace, platform tags and a command line tool just smart enough to fetch and run zero-dependency applications that fit in zip files then that should specifically be a Rust/Go effort. We’re not going to solve cross-language cross-platform package management with this.
