debugfs is already under /sys.

If /dev is not popular, then how about dedicating a location (say
/kernel) as a base for mounting virtual file systems? So cgroups can get
/kernel/cgroup. hugetlbfs is often mounted on /dev/hugepages but that
does not seem to be standardized as well, so it could be the second
citizen under /kernel. configfs could be moved there too. Having a
different rule for every new virtual fs does not seem to be a good
idea...
