Yeah, my GitHub Actions workflows don't do much more than `cargo build --release && cargo test --release`. I don't use any of the fancy features that would lock me in.

It's really just running the tests on Mac that I rely on it for. For Windows and Android, I can (and regularly do) use wine and qemu-user-static to run the tests on Linux. My project (a computationally heavy CLI tool) is simple though. It doesn't need much from the OS besides memory allocation, thread spawning, and opening a user-specified file.
