It seems neat on the surface but it also seem to involve two redirects, first one to google.com (which is not obvious and personally not something I would like), and then to MDN. It would be cool if it linked directly to the page on MDN or showed the content directly within the page.
And the second time I clicked I was met with this message, not mdn.io's fault but nonetheless (i.e. "google police" - not sure what they mean with "unusual activity", there is hardly any at the moment - maybe not enough? :) or maybe I just got a busy vpn exit point):

Yup, that site seems to be basically redirector to Google redirector [1].
You can get the very same effect like DuckDuckGo keyword search but with "just the last redirect" with vanilla browser bookmark [2] with `%s` interpolation:
If you go to chrome settings -> Manage search engines and define a new search engine with Keyword: "m" and
"URL with %s in place of query": https://www.google.com/search?&q=site%3Adeveloper.mozilla.or... typing "m await" in the omnibar will jump to the first google result from MDN, which is what it seems mdn.io does.
