The relationship that is naive to assume is the correct one, but isn't 
fully implemented yet since, as you've noticed, there haven't been any 
hs -> master integrations in JDK 10 yet. (We're working on some new 
internal infrastructure to support integrations and it isn't fully in 
place.)

Having integrations occurring is a precondition for the planned repo 
consolidation, which is targeted for September:
