You can disable a channel when using activation keys, much as with 
Spacewalk I would assume. You can also populate channels in an automated 
fashion. Both with RHN and Spacewalk.

With an emphasis on *if*.

And the same will be true for RHEL. So when we make CentOS different from 
RHEL, the documentation for both may become different in that area. Is 
that what we really want ?

Also if CentOS would become identical to RHEL, it may change the dynamics 
and reasoning for (preventing) incompatibility changes. So I think there's 
a good reason for keeping things compatible. Whether people want to use 
RHEL/CentOS with RHN Satellite or using RHEL/CentOS with Spacewalk.

We can not base decisions on things that may or may not happen in the 
future. In fact, keeping things identical to RHEL protects us from 
changes that will happen in the future. Nobody can blame us for being 
identical to RHEL.

People may blame us for deviating from RHEL, which is what we will keep on 
doing if we leave the RHN libraries/client out.

Although I don't think I will be changing your mind, Marcus, because for 
your use-case there is no benefit.

Kind regards,
