You are describing the situation today and making it into a contract. You need to be sure that it is policed and enforceable.
Meaning there need to be tests to ensure it stays that way and that it is not an unreasonable constraint on changes in the platform.
Also what if anything do the jigsaw team recommend ?

Also, it might be just as easy to have the class files and the natives in one downloaded jar file per platform, since at least the natives need to be platform-independent. I'm far from a maven expert, though, so I don't really know for sure which path is easier.
