Per the INN NEWS file:

  * To simplify anti-abuse filtering, and to be more compliant with news
    standards and proposed standards, INN now treats as control messages
    only articles containing a Control header.  A Subject line beginning
    with "cmsg " is no longer sufficient for a message to be considered a
    control message, and the Also-Control header is no longer supported.

It causes problems with regular Usenet groups because a lot of filters
don't know to look for Also-Control and a lot of automated programs only
look at the control.* groups and wouldn't find the control messages.
