At the moment, to my reading of the code, the ACL support is not
implemented correctly (wrong owner of created objects). The tests I
described in my last mail would confirm if they are or are not, and
given we have had to go over that particular issue twice already, we
really, really should have an automated test for that.

For all the huffing and puffing over this, I've not see any progress on
any of the testing requirements I've suggested. I'm sorry that everyone
else seems to have promised Kai that he could switch this on by default
as soon as the code is complete, but without that testing, my position
remains unchanged at this point.
