My mind was not changed, sorry. First, RFC 822 is obsolete, and RFC 2822 does
not contain the quoted paragraph. Instead it says that '[w]hen
the "Reply-To:" field is present, it indicates the mailbox(es) to which the
author of the message suggests that replies be sent.' - the author, not the
mailing list software. There are other fields for that.
The rest of the arguments assume that lack of a "reply to list" or "follow up"
command is the natural order of things. Sadly, almost no mailers do provide
such a command, but munging Reply-To doesn't exactly increase pressure on
vendors to implement it.
I guess this is a fight between ideal and reality, i.e. between agreeing on a
direction and going there and staying where we are because no single
individual has an incentive to take the leap. This is where the market fails.
Interestingly, Kmail seems to have some "anti-munging" feature - when the
Reply-To address equals the List-Post address, I guess, the reply to author
command ignores the Reply-To field. This doesn't work on some other mailing
lists I'm on, which don't have List-* header fields.
