This is a gentle "+1", please, for same list name across multiple
independent domains; those lists operating independently.

(It's a topic that keeps simmering in the background... there was a little
discussion of it a few months ago.)

We have our main university domain "@durham.ac.uk".  But we also have
several related other domains (collaborative ventures) which have other
domain names.

In that sense we resemble an ISP offering multiple independent domains,
and offering mailing lists "@" each domain.

For several years we have run majordomo.  Although that has several
drawbacks by today's standards (hence our starting to migrate to Mailman!)
one thing majordomo can do and where Mailman currently falls short is to
handle (and quite naturally so) multiple "@domains" and to support the
same "listname@" (same name, totally independent functionality) on them.

So I certainly wouldn't classify "list at dom1" and "list at dom2" (same name
"list") as 'quirky'. Rather as 'routine' for an ISP-like organisation
offering multiple, logically independent domains.

Put another way: at a single domain site, the uniqueness of "listname" and
"listname at domain" are equivalent.  At a multi-domain site (e.g. a
multi-domain ISP-like body offering maillist services), the uniqueness
criterion has to be the full "list-A at dom-X" ("list-A" is insufficient).

And I hereby match my "+1" request with a "+1" offer to help test and
debug (so far as I reasonably can) any related beta code from the Mailman
