Why is ipp mandatory as protocol for browsed printers?

[Christer Bernérus]

The browse protocol states that the uri must begin with ipp://, and cupsd enforces this. As cups is built, there is a one-to-one relationship between the protocol part of the uri and the cups backend. This means that there is no way to use a custom built cups backend to accept browse packets.

Why is there such a limit ?
