I'm not sure what to put here. Lee Byron says
The root value represents the "top" of your metaphorical graph of data, and is useful to include functions or data to help resolve the root fields in your schema.
I've personally never had the need to use rootValue. It seems like Apollo's SchemaLink has it as an option

I think getEnveloped should be called per operation instead of once.
Because the lifecycle in Envelop is handled per operation. So it would be better to call it inside the link.

Let's call it only EnvelopLink.
EnvelopSchema seems extra :)

We don't need this I guess.

Do you think we can also support subscribe ?
Also keep on mind that execute can return AsyncIterable.

This can be similar to this one;
