I wouldn't get hung up over this. In the Q&A [1] it says that there will 
be "a mainline 7 repository that will always be open for putbacks". 
Assuming that this mainline forest starts out as a clone of jdk7/jdk7 
then it will have all the history and I assume would be equivalent of 
just continuing jdk7/jdk7 into the future. There's isn't too much detail 
on how specific updates are handled. It looks like the proposal is to 
clone from the mainline periodically and presumably that is where the 
end game polka and stabilization will happen. The changes will need to 
get merged back into the mainline. I've no doubt HotSpot will need 
special handling but otherwise the overall approach looks reasonable to 
me. The proof will be in the eating of course and the approval process 
to get changes into mainline (or an integration forest that feeds into) 
will need to be simple and fast.
