I think it would be helpful. Being able to say that the magic resides
in the first 8 bytes for all our codecs is a plus when it comes to
parsing and consistency. We could go for 9 instead, but that's
somewhat of an odd number...
I don't think the \x80 is too much of an issue, but I don't know what
that packet type field is really used for.
