Generally speaking, ordinary posting agents do not have any capability to
create Control messages, except in the case of cancels for your own
articles.
Issuing 2nd and 3rd party cancels and group control messages is too
dangerous a tool to allow ordinary users to access it. People who have
good cause to do it had better understand exactly what they are about, and
they should do it manually, or with the aid ot special scripts written for
the purpose.

And was "cmsg cancel" a documented feature of youe user agent at that
time?

Those sanity checks are quite standard across all user agents, and USEAGE
encourages exactly that, and no more.
