I've said no such thing. If you want to take the code, take it. The SGA license has been explained by me, by Matt, and also today on the Apache legal-discuss mailing list. But since this code as not been reviewed you take it at your own risk.
If you want a fully reviewed code base, then you'll need to wait for an official release containing that code. But no one is forcing you to wait for the release.
And if you think the wait is too long for your purposes then you are welcome to help us integrate it. But no one is forcing you to do that. You can always just take the un-reviewed code as is. Or wait for a release.
So the choice is really yours.
What you cannot do, at least not with any respect or credibility, is refuse to take the code as-is, refuse to help integrate it, and just whine about it endlessly.
