Should @component fields take two parameters?

[rbalicki2]

I am considering having @component fields take two parameters, a la:

iso(`
  field Foo.Bar @component { id }
`)(function(props, additionalProps) {
});

Pros:

• props will be automatically typed, and additionalProps can be provided a type by the user. I don't see a good way to type the remaining props otherwise, without having the user import the generated type Foo__Bar__param

Cons:

• It doesn't "look" like a component, so some people will be put off by this. Maybe some tooling will not work, e.g. eslint rules might complain about calling hooks. I don't know.

I have concluded that this is feasible and a good way to go. See the branch rb/demonstration-of-two-params for a demonstration: https://github.com/isographlabs/isograph/pull/new/rb/demonstration-of-two-params
