Apache Karaf with OSGi works pretty nice using annotation based dependency injection with the declarative services, removing the need to mess with those hopefully archaic XML blueprints. Too bad it's not as trendy as spring and the developers so many of the tutorials can be a bit dated and hard to find.

What you're looking for sounds like AppImages (https://appimage.org/) . I have only used them while downloading games from itch.io, etc. (since I prefer package managers) but they seem to work out of the box on popular distros. - Source: Hacker News / 4 months ago

Ideally a new instance of the application is installed for each user. This also provides better isolation if one user upgrades/removes/breaks their application instance.

Although I haven't used plugins feature myself yet, this does sound like the perfect use case for them. Not every patient needs to access every single source.
