Interesting idea, but I think thread splitting is less of a concern than
diluting the meaning of a patch by including a lengthy change log with a
fraction of the text being about the code that follows.

I think this is the reason for a cover letter in the first place; not
just version control.  After all, we could tack the version information
into the first patch too and avoid it being in the final commit message.
