Why do you say this?
They are fine, terrific, and specified for avant-garde installations where equipment can be sensitive, namely, computers and such electronics.
"200% neutrals" we call them.
Parallel equipment grounding conductors aren't a big deal
They are also fine so long as they are all headed to the same place with sufficient ampacity to get the current there.
Iso grounded recepts for electronic equipment are not only OK but are desirable.
True depending on just how isolated they are.
The grounds still must come together at the point of service.
But say if you use a bonding screw in the disco and use a bonding screw in the load center and you have used 4 conductor wire between the disco and load center, then the EGC will carry current as the GC does.
Correct.
That would be a faulty installation if the neutral and ground were bonded downstream from the point of service.
I always run an EGC ... {that} has the ampacity required for a dead short ground fault
I like that for a lot of reasons.
