While I think it would be entirely reasonable for an rMUA to take the
presence of BCC as meaning that the rMUA should not allow a reply
command to automatically include TO or CC, I do not believe that it a
common rMUA behavior. In fact, I've never heard of it.
In the earliest version of MH (pre-Rose), the posting command sent the
BCC copy separately from the To/CC copy. One of the things is did was
to make To and CC be [To] and [CC]. So they looked like normall to and
cc fields, but the reply commands did not see them present.
This got removed from later versions of MH and I haven't see anything
similar since then.
Accidentally copying to the to and cc folks is certainly an important
issue.
