If that is the intention of the authors of this draft, they will have to
fight me :-)

I do not see why an in-band control channel for a PSC network would be
made a RECOMMEND, SHOULD or MUST.

Yes. But more precisely, one must avoid using the control channels for
data traffic. Even in-band control channel may use a different address
space, and those addresses must not be used for data.
