I don't see a reason to block vhost-user.rst changes during QEMU's freeze.

I get a sense that this is about politics in the end. Do people feel they are not represented and would like to have more influence in the vhost-user spec? You bring up project neutrality and a model where Michael is no longer the sole maintainer. It will be necessary to propose a concrete roadmap and also to explain the concerns about neutrality more so it's clear they won't be an issue anymore in the future system. Why is the current system not neutral and how will the new system solve that? Who should be a co-maintainer? Stefan
