Ok, I went and found what I'd read: http://www.theverge.com/2016/12/8/13878444/google-home-devel...

> The first and most important difference is that Google is not going to create an “Action Store” where users can select which ones they want and “install” them on Google Home. Instead, Google itself is going to approve all the keywords that developers want to use to invoke their actions and make them all available to everybody.

> That effectively means that actions will be curated by Google (like an app store), but users won’t have to install anything before using them (like the web). “It's not a direct analog to any existing ecosystem,” says Jason Douglas, director for actions on Google.

That article does specify that there will be a hand-off to 3rd party systems, rather than Google orchestrating everything, but it still sounds quite tightly constrained and I think that if the plan is to have things all work nicely together and not be silos, then tighter integration with more Google control will be the name of the game.
