Seeing as quite a few mailing lists alter the messages (adding 
footers, tags, and sometimes even ads), stripping signatures 
should continue. The alternative would be to leave the signatures 
even though verification is virtually guaranteed to fail.

To me it makes a lot of sense for verifiers to change their 
behaviour when there are clear signs that a message has been 
forwarded by a mailing list.

We verify in our general anti-spam filter. That filter acts 
differently on failed verifications if it find some list headers 
(for example List-*).

Seeing that people have discussed what list managers should put 
in the Reply-To: for years without agreeing, I don't think you 
should hope for a consensus on another address swap/change.
