Problem

Many of the Request Network packages use default exports meaning that user code applications have to import the whole package even when using a small portion of it.

Ideas for Improvement

Continued from #1023. Enforce no-default-export ESLint rule for all packages, not just utils. Replace default exports with named exports.

I concluded that there isn’t a strong enough motivation to actually do this task so I’m labeling it “not planned” and moving it to “Done”
