In organizations without any low-overhead mechanism for maintaining
group mail lists, people will often resort to using a Bcc: header
with scads of addresses. Often those folks with put themselves in th
To: header, but sometimes it's left blank.
That's the only remotely legitimate use I seen of headers as you
describe them.
