Yes, I found it:
And I made a mistake in my previous text. It is about port group, which is
what we need here, rather than ACL group.

Yes, if we have the capability to represent port group/set in ACLs, then it
is possible for ovn-controller to translate into flows using conjuncture,
but maybe it is a less valuable optimization since most ports from a group
are not landing on same HV.
