The change I propose is not driven by considerations concerning pro or con
open/closed setups. Maybe you misunderstood me or I am misunderstanding your
reply.

To clarify: I don't want to require users to authenticate in order to allow
them to send. I want mailman to use a stanardized port for message submission
(and that brings in the authentication requirement).

Everybody seems to use a dedicated port to inject messages coming from
mailman. People do that either to completely avoid applying expensive content
filter rules to all messages coming from mailman or they do it to only run a
minimal subset of content filter rules.

I want to standardize that dedicated port and I propose to use the submission
port as recommended by RFC for scenarios like that. The authentication
requirement applies to the mailman server (read: SMTP client) only. It can be
set once in the global mailman configuration file. Users don't need to do
anything. It's completely transparent to them.
