Yes, I only requested that people not change the subject headers for
trivial reasons, by which I meant things like fixing typos (as in the
subject header change that brought about this thread). I also only
intended my request in the context of this forum, which is shared
between Usenet and mailing list users. Changing the subject header to
indicate a change in subject is, of course, fine.
