An odd claim, since this is the fourth ? level of email reply.

I'm not sure I parse your here. The core fact is there is no "thing" in 
the CAMSS block that can be modelled as a provider to JPEG in lieu of 
TITAN_TOP_GDSC.

That GDSC is provided by CAMCC not by any other silicon block. So 
omitting power-domains for individual nodes is incorrect. Best practice 
and in fact the _only_ practice that can work is to list power-domains, 
interconnects in the individual nodes themselves as - I've pointed out 
multiple times now - those blocks have to ramp clocks and scale voltages 
dependent on their particular use cases.
