Howdy,

I still see these just as new dependency types: "module", "agent",
"doclet", and so on.

Also, for "other end" (producing) we'd need new packaging as well: "module"
at least for example.

ArtifactHandler would need to be extended as well, or better, complete
adopt Resolver ArtifactType instead (of limited Maven ArtifactHandler):
https://github.com/apache/maven-resolver/blob/master/maven-resolver-api/src/main/java/org/eclipse/aether/artifact/ArtifactType.java

And plugins should just do what given Artifact's ArtifactType says, no
more, no less.
No heuristic, no "guesswork", or anything like that, just keep the simple
stupid.

Thanks
T
