Existing unfixed versions are already released in various releses. C version of virtiofsd is already being used in RHEL8 release and some fedora releases. And rust version of virtiofsd is supposed to be in RHEL9 beta. Hence if we change it now, it is possible older virtiofsd (unfixed one) is running on host and trying to boot a newer guest kernel and that leads to breaking things.
