By definition the grid is decentralized. That’s what makes it a grid. Resiliency of the grid is a function of excess capacity but not the number of nodes.

I am no expert but remembering the grid outage in Spain this year, which was caused by a substation or node failure and not by a capacity problem. Wouldn't it be fair to describe resiliency as a combination of both capacity and nodes?
The Spainout was caused by having too little rotating mass in the grid that stabilizes the frequency.
There was a trigger in some of the PV systems, but that wasn't the underlying cause.
Yes, interconnectedness is critical if you want reliability.
Spain has far too little transnational capacities. That was a significant contributing factor in the grid outage.
If you want to change the topic of this conversation to distribution resiliency instead of production resiliency then sure.
I had both of these as a single concept in my head, thus the confusion.
