Although I agree that maintainability of these packages is going to be
hard, I don't think it's so different from, say, maven :)

Using Gradle would be the best solution here, but unfortunately, it
depends at least on Kotlin for which there is currently no known
bootstrap path. I've ended up building a 0.10.something version in a
channel, but the next version I tried to build failed for unknown
reasons (I think the previous version miscompiles the last version I
could build). Even so, building from these old versions would require a
lot of intermediate versions before we reach a recent Kotlin and it'll
get worse everytime. I haven't found an alternative implementation we
could use either. I don't see Gradle coming to Guix soon unfortunately.

Using a separate channel wouldn't change the maintainability issue, and
it would make openjfx much less discoverable, so I don't think it's a
good solution.

We should simply add more documentation and make sure we explain what's
going on. It's difficult to follow, issues will be hard to fix, but I
think it's pretty similar to Maven, where each upgrade brings new
issues that are difficult to trace back to a cause and fix.
