It appears perfectly reasonable to me that stateful connection tracking may
lose connections over a reboot. Yes, this is inflicting pain on the user, but
on the other hand, it is supposed to be a firewall which is blocking what
isn't allowed...

If you don't want that, don't use stateful filtering.
