It seems that there hasn't been much going on concerning the LXC package(s) in Debian 9 Stretch. The version is stuck at 2.0.7 without any patches backported since Jan 2018. Yet there are known (important) bugs which break LXC on Stretch.
Even in backports there is the following note in the changelog of the lxcfs package:
lxcfs (2.0.8-1~bpo9+1) stretch-backports; urgency=medium
* Team upload
* Rebuild for stretch-backports.
* This backport release is an alternative to 2.0.7-1 that has a couple of
issues, and shouldn't have reached stable.

Although this workaround seems to work for some, it doesn't work for others including the author of the last comment in bug #888647.
Meanwhile LXC 2.0.9 is out since October 2017 (yes, 2017). Instead of keeping a bugged 2.0.7, wouldn't it be better to include the latest upstream version of the 2.0 LTS branch?
Note: LXC itself works fine for privileged containers _without_ resource lmits. But as soon as resource limits are used, this bug comes in place and breaks LXC.
What's the current status with LXC and its related packages in Debian Stretch? Can we expect a new upstream release, a bugfix or a new version (3.0 LTS) made available in backports?
Thanks in advance for letting us know.
