I sort of agree with you, but the motive I'm not sure I agree with. "renewables don't want to be reactive" doesn't feel right.
The challenge here is technical/control. There probably is no heuristic you can make at your home to know how to nudge the power phase/reactivity, or to supply less.
I think renewables probably could be enormously helpful and probably wouldn't mind, wouldn't be very hard for them to help shape the power!! They are vastly more flexible at inverting power than any other power source, are very readily programmable.
But most renewables don't have the whole grid view, would be guessing wildly based on local conditions that don't provide adequate information to show what's really happening to the power network.
I hope over time the idea of the Virtual Power Plant related infrastructure starts building good protocols, starts being able to ask for what it wants from who it wants, providing some of the coordination necessary to take advantage of the enormous flexibility that renewable power, with its digitally dictated power delivery, bring. I think renewables would be amazing and happy to help here, if there were better information flow.

This is how other power generators are working. You don't really need a whole grid view either to make these decisions based on your local interconnect. You do, however, need either some pretty fast electronics and inverters or a reliable system that responds correctly to frequency demands. Making it smarter isn't entirely helpful.
