What is the default value of a requests client?

[bzbarsky]

Spec at https://fetch.spec.whatwg.org/#concept-request-client says:

A request has an associated client (null or an environment settings object).

There is no "unless stated otherwise" clause, but there is also no indication what the client should be set to when a request is created. I assume it should default to null, but it's not 100% clear.

The expectation is that everyone that creates a request sets this field to a value. In a way this might be a duplicate of #186.

Would it make sense to require this value to create a request at all, then? That is the "create a request" algorithm would take it as input. That would make it a lot easier to catch cases where people are failing to set it, I'd think.

Yeah, I hadn't really created such abstractions yet since not everyone adopted Fetch as their infrastructure (e.g., CSS).

We might have enough usage now though to figure out how to refactor various aspects.
