While it does not strictly concern this PR, we should note that the CI test test-sys / Build and test C-API on macos-x64 (pull_request) failed - I think re-running it might pass - but also printed this warning:

Warning: The `save-state` command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/
Error: The operation was canceled.

error: Please, change the owner before deploying or check your current user with `wasmer whoami`.
