This is an understatement. With fetch available in node, we have a single, standardised, promise-based HTTP client Interface available on all (more or less common) JavaScript platforms.
This is great news for an ecosystem traditionally extremely fragmented and may lead the way to more consolidation in the JS library space.
NodeJS API are traditionally not promised based (although nowadays some do offer a promisified option), so I'm not especially excited to have a promise-based API :)
It's a great news for people doing both front end and backend I guess, but for people doing NodeJS développement it's just one more option to do http request (which I guess is going to be very similar to the module node-fetch that have existed for a while, without special consolidation effect)

...and that's part of why this is great news. Node APIs are the avocado colored appliances of the JS ecosystem.

I think the only benefit it that it makes it easier to share code between front end and back end.
