    Considering diffserv as QoS supporting mechanism, I am

MAny already are, I believe telnet and ssh are for example.

    By this I mean the applications automatically send
    out their packets out of the box with appropriate dscp values
    depending on their QoS requirements. While tc is one way of
    achieving the same result, it is an external mechanism requiring a
    seperate agent to configure diffserv.

    My wish is, all the future netapps
    from Linux should take advantage of QoS as applicable, naturally.

As I said, some (many) already do... QoS means different things to
different people.  Nice idea in theory, in reality its not worth much
to acheive what you want.
