Will Virtualization of FreeNAS EVER be a good idea?

I know that in the current state of FreeNAS, virtualization is a bad idea. My question (aimed to those in the know) is: will it EVER be a good idea? Might there be some improvements coming down that would tend to make virtualization a worthwhile and safe endeavor?

Please don't flame about the very well-known stance that virtualization is a VERY bad idea... I'm speaking about future directions.

Thanks,
Dave
