Yea, you do. Sadly you've just gone 6 levels over the head of Sandy the PR person. And that's why it's still the default, because it works for everyone.
Don't you dare start putting reality in the way of my geek fantasy!
You've got a point, and throwing mutt at your typical office worker might not go far. Then again, my (very technophobic) father was dealing with mainframe-based "business productivity tools" in the 1980s. Including some (by current standards) very, very clunky email tools.
I'd throw the problem at Apple. I think you'd find that they'd figure out a way to sort out when it made sense for someone to forward an entire thread to someone and handle it that way. Probably, these days, within a Web interface, though possibly through a mail client / app.
