During the Scientific Python Developers Summit 2023, there was interest to use GitHub Actions workflows from here, particularly for wheel building. Even though the immediate need at the summit was a simpler workflow than what is supported here, it is undesirable for Scientific Python to reinvent the wheel when OpenAstronomy workflow is generic enough to be upstream and can be beneficial to the wider scientific Python community. Are you interested to collaborate with them?
