it's stupid because by your same argument (300x5=1500, i.e. maximal amount of attachments per posts) the result will be a thread with all attachments at the front followed by text-only replies
nobody wants that, the thread will be abandoned and a new one created
the same outcome (phasing out of threads) can be achieved by simply reducing the maximum amount of replies, and if that is not desired, the maximum amount of attachment per post can be reduced instead
