FVD isn't merged because it's gotten almost no review. If it turns out that it is identical to an existing format and an existing format just has a crappy implementation, it wouldn't be merged in favor of fixing the existing format. But if it has a compelling advantage for a reasonable use-case, it will be merged. I don't know where this whole discussion of "strategic formats" for QEMU came from but that's never been the way the project has operated. Regards, Anthony Liguori
