Yeah, although distributed power generation is an actual solution to reduce transmission loads, I agree that it's too soon. It is very complicated (but I think doable!), but even then probably takes too much space for populated areas.
I like the idea of knowing if a transmission line is hot enough to start a fire, but that isn't a substitute for new transmission capacity from remote PV farms or just to be more resilient.
Space, cost, reliability, of course it's complex to integrate new generators that require communications to work together properly alongside planning the real wire infrastructure.
I believe it can be done, sure, but it's still complex and utility companies are not a fan of complexity.
