What is the remaining punycode from dependencies? Let's solve it. This warning is very annoying :(

[DmitryAnansky]

async function streamToBuffer

Its within dev dependencies, not sure why they got to compiled version.
Maybe they will be gone with the released version.

(checked on 22 node)

The smokes don't cover anything specific to fetching data, only basic operations in different environment.
