EnzymeCore is an unconditional dependency.

I just noticed that #2281 also added EnzymeCore as a full dependency, next to it being a weak dependency. That defeats most of the point of it being a package extension. I guess it can just be removed from being a full dependency?

@wsmoses This blocks a 5.3.4 backport release, which shouldn't introduce new dependencies.

Hm that's the default extension pattern to make things work prior to 1.10

We can drop it of course, but it will gate functionality on that.

I don't think it is? Pre 1.9 we used Requires, which doesn't require a dependency
