Hey!
Author of the flatpak here! I'm not associated with MMOUI but I did speak with Dolby about this topic and he knows of the existence of this. The raw CDN URL for Minion isn't actually available on the internet normally but he did give it to me in a DM so there's not a constant 'needs to be updated' window popping up.
The JavaFX assumption is correct. I did make a WIP/Template PR which uses OpenJDK JRE 17 and OpenJFX manually installed on top of it, and while it does work it takes around ~10MB or ~20MB more. You can find more information about the process here:

There was some talk about making a bit more official but the conversation was halted (rather, I got ghosted
).
