The former, I'm afraid.

The conclusion doesn't seem like such a good idea, well, at least to
me for what it's worth.  Conclusions at summits don't carry decisive
weight.  It'll still have to prove its worthiness for mainline all the

expanded area now covered by virtualization, the arguments in this
thread don't seem too strong.
