From a safety perspective having N-G loops is safer than not having grounds.
The basic issue with relation to current code and best practices is current passing through the ground rather than neutral under load. Ideally all current returns to source via the neutral and not the ground.
My Opinion, not advice:
Go to anyone's house in the US and put a clamp meter on a ground. I bet you 99 times out of 100 there's current going through it because our world is imperfect.
There are two issue IMO with this.
One listed above is creating Antennas that interfere with other devices both in your home and in your larger area.
The other is ground wire sizing. If you have current returning to source via the ground, you need to at minimum be sure the wire is capable of safely handling that load.
Some may point to safety concerns of working on a system because if you detach a ground in a multi-loop system you haven't interrupted the circuit.
I would argue this is a nanny state mentality of trying to make everything overly safe. If you're working on any electric circuit it is your responsibility to understand and test what you're working on before you start taking it apart. For your own safety, not to satisfy some words on paper somewhere.
