I've been in contact with Dolby and now Minion is both verified on flathub and it's an official download source under
minion.gg.
Edit, DONE: I'm waiting on some PRs for flathub-specific tools to allow permissions for
xdg-data/Steam and then I'll merge some branches to make Minion be delivered by the Flathub CDN, causing smaller downloads during updates and an automatic update job via
x-checker-data. Meaning no maintenance won't ever be required except in critical changes where data structure or the JRE needs to be changed.
Speaking of the JRE potentially being changed, I've created a template PR for JRE17 LTS so in case it needs to be done it'll literally only take a handful of minutes to do it (primary focus is making it work on aarch64 as well for future Asahi Linux users).
