I'm on a team that's currently shipping a Godot 3.5.1 game across Linux, macOS (universal), and Windows.
After sorting out a couple minor snags in the build process (particularly around getting cross-compilation to work on Linux in GitHub Actions, and library validation entitlements for code signing), the finished builds work wonderfully on the M1 machines we've tested with.
