I hadn't considered that -- while it's potentially a way to appear less spammy, since isn't actually visible to the user, it's free to become a dumping ground. Yikes.
I wasn't thinking of truly unusual ones, though IIRC back when I was reading Usenet some people would use those as a sort of easter egg signature. But I think that was before Bayesian spam filtering became a big thing? I was mostly thinking more usual things like X-Face and X-No-Archive and such. Yes, you can see from my choice of examples that I'm really thinking more of Usenet than of email. :)
Having a whole conversation in one window does seem convenient, but IINM it collapses the tree down into a linear thread so obviously I'm wary of that. :P And in cases where you really are looking at a lot at once, I doubt scrolling up and down is actually that much easier than switching back and forth between messages, especially if you bother to open them up in separate tabs.
