It could, but the whole point we are trying to get across is that it 
adds a pretty large maintenance burden. As has been said before in this 
discussion, it hampers development. Javac is no small part of OpenJDK 
and as Alan pointed out, there are other easily forgettable details that 
get more complicated. To truly support it would require frequent 
verification that all bootjdk versions work and produce the same thing. 
We are in no need of more build configurations to keep track of. Are you 
up for taking on that work?
