After #488 we will have two packages (nyc, whatwg-url) pinned to an older version due to the fact that the new version does not support Node.js v4.x, and another one (url-search-params) required only for Node.js v4.x as newer versions of Node.js support URLSearchParams. We should update the list of dependencies for node-fetch v3.x, which will drop compatibility for Node.js v4.x.
