They're ~ 26 years old now:

That said, I think Thunderbird is an outlier here too.

But either way, the issue mentioned in that Reply-To piece is still
relevant now, because the exact argument is that munging the reply-to
header to the list's address (which is not necessary in the case where a
mailer supports a direct "list-reply" option) is harmful because you
could reply to the list when you're trying to reply to the original
sender _exactly_ applies in this case.
