Years ago, it was a surprise to get certain results like the calculator for questions like "how many is eighteen plus twelve" but those days have long passed and Google are adding new tools regularly. I think (and there are plenty of references that agree) that many of the earlier tools were effectively Easter eggs as they were "hidden" and unexpected, but tools like the "color picker" are just that - tools, added to surprise nobody, that provide only reasonable and expected results.
While we have a duty to ensure as much of the content of Wikipedia is referenced as possible, we are not bound to ensure that every claim in the media is transferred to an article in the encyclopedia; just because a magazine says "ooh look, Google added a new Easter egg", it doesn't necessarily mean their clickbait hyperbole is accurate and we need to add it to the list.
As, although they may not have been announced ahead of publication as planned initiatives, they are basically expected behaviour now; focussing on the embedded tools section, are there any we can agree are or were not really Easter eggs? Fred Gandt · talk · contribs 17:38, 3 April 2019 (UTC)
