I don't know what the roadmap for this project is, and if it's intended to be published on WordPress.org or not, but while it is available only on GitHub, please consider implementing an update mechanism whenever a new "stable" (whatever you want to call stable) version is released.
I often use https://github.com/YahnisElsts/plugin-update-checker, and it's pretty simple to implement. I'm using releases, but you can use tags.
Keep up the good work.
