Logout request -- reason?

[Luben Tuikov <luben@splentec.com>]

I was under the impression that byte 1 in BHS
is a flags byte -- i.e. bit values.

I now see that the reason code is moved exactly there,
in the Logout request PDU. 

Could anyone please explain the logic behind this?

At the same time byte 3 and 4 are reserved to 0.

Why don't we:

1)  Move the reason code to byte 1. This will
    make it _consistent_ with the response byte
    in Logout Response.

2)  Make the value start at 0x80, as to hide
    the ugliness of F = 1, and the fact that
    we are trying to fit a numerical value (!)
    and a bit value (!) in the same octet.

Comments?
