The idea is to split threads (defined by References) at subject changes,
so that you have a new thread whenever the topic of the thread changes.
On the other hand, in email discussions the subject is often all you
have.
IMO that should be left to implementors (or the user who chooses between
different threading styles). USEFOR should just define the References
header and USEFOR or USEAGE the "Re: " prefix. (It does not matter which
specification does that -- maybe USEFOR should import the description
from RFC 2822 while USEAGE defines more restrictions.)
