I think forwarding should be more symmetric with replying than with
sending a new message.  Forwarding is an act of sending a mail you
received at your account A to another person, and so the default account
that it's sent from must be account A, not one of your other accounts.

Isn't it really weird if a mail was "forwarded" from an account that
never had received that mail?

I'm not surprised because it's a new mail and not associated with any of
my accounts yet before I send it.  Forwarding is different because it's
already associated with one of the accounts and that one should be the
default From address when forwarding.  That's my expectation and I think
it's intuitive.

Agreed that this issue can happen in this case.  Let's forget about the
privacy issue.
