Currently the a general nack from gregkh on such work.

Given that sysfs is almost never a fast path I suspect it makes most
sense to filter sysfs in some way (aka bind mounts or fuse) and present
the results to the container.

At the point this is something that we are using a lot and have
demonstrated the usefulness of it and it appears a kernel level
solution would be better it would be worth reopening the disucssion.
