No, I don't think so. Assuming there is no Followup-To header, a
newsreader will direct all followups to whatever was in the Newsgroups
header. It will take no notice at all of what group it thought it was
reading at the time, or of what was in any Xref header (posting of
completely new articles is a different matter, of course).

Surely, noone is suggesting that the Newsgroups header be altered? That
would be totally contrary to the fundamental "dont't tinker after
injection" policy that permeates our whole draft.

So followups in existing threads will tend to get posted to oldgroup,
except insofar as participants correct them manually. That is why it is so
desirable that servers should nevertheless make them appear in newgroup,
by the use of the aliasing mechanism or otherwise. The users of such
servers should hardly notice any difference.
