Looks like my answer covered In-Reply-To but not User-Agent.

It appears that the analogy(s) for User-Agent for my E-mail
client might be one or both of:

Mime-Version: 1.0 (Mac OS X Mail 16.0 \(3731.400.51.1.1\))
X-Mailer: Apple Mail (2.3731.400.51.1.1)


I'll also note that I've always read the list via the likes of:

https://lists.freebsd.org/archives/freebsd-hackers/2023-March/date.html

So I'd not seen the "by thread" mess.
