Hm that’s an interesting question and kind of hard to speculate on. Before LDK came along I didn’t think an enterprise-first style implementation would exist and now we have one of those with phantom nodes and other cool scale based features.

I think pretty highly of the existing Lightning devs out there. If they won’t add a particular feature I suspect there would probably be a good reason for not doing it.

In the near term it does feel like there is just a ton to be done and too few to do it all. But perhaps one day lightning will ossify and we’ll look be able to look back and say oh hey it’s done.

I don’t see a day like that coming anytime soon though.

One area Lightning devs aren’t working on is automated channel management and rebalancing and I do suspect that area will see some pretty awesome innovation over time. If that progress well, and I suspect it will, we’ll eventually have one button lightning node deployments that just do everything for you automatically.
