I thought we got agreement years ago that containers don't exist in
Linux as a single entity: they're currently a collection of cgroups
and namespaces some of which may and some of which may not be local
to the entity the orchestration system thinks of as a "container".

I wasn't party to that agreement and don't feel particularly bound by
it.

That's not at all relevant, is it?  The point is we have widespread
uses of namespaces and cgroups that span containers today meaning that
a "container id" becomes a problematic concept.  What we finally got to
with the audit people was an unmodifiable label which the orchestration
system can set ... can't you just use that?
