Sure, I'd hope for a heavily decentralized system to have some capability of autonomous operation. But in the medium and long term, it can't be good to not be able to remotely monitor for failures requiring manual intervention or on-site mechanical servicing.
The problem is once again our godawful prior government. Many tens of thousands of jobs in the wind industry have vanished over the last years [1] because the Conservatives oppose renewable power and impeded it wherever possible - if it is because of corruption, incompetence, fear of the far-right that outright demonizes anything not fossil or nuclear I don't know. In any case, we simply don't have the staff to visit literally thousands of wind turbines, a lot of which are actually offshore, simply to replace routers.
