Apparently there is; reply-all seems to have become the norm over the
past 20 years.  I used to rail against it but I gave up.  Now it seems
some people (mainly younger people, perhaps) regard it as rude if I
_don't_ CC them on mailing replies.  Maybe they fear being ignored or
circumvented in decision processes.

Years ago, the header "Mail-Followup-To" was developed as a convention
to get this under control.[1]  Maybe because the maintainers of GMail,
Outlook, and other web email portals that provided spam filtering
services, found themselves with better things to do than support it, we
arrived where we are today.  :(
