Similar from what I can tell with CloudSearch being superceded by Elasticsearch Service. Although their version of elasticsearch is ~2 years old and hasn't been updated since they launched the service, so this may be a case where neither are getting any attention.
The worst part is, AWS support is so tight-lipped in the forums and over web support that there's no way to tell what is still fully supported and what's being silently put out to pasture. You have to look for hints based on what products they're doing webinars about, looking at the momentum of what products they're making tweaks to in the weekly update emails, etc.
Interested to know because we're considering cloud providers.
Isn't there usually some sort of "disclosure: I work for Google"? Your post-history seems very one-sided. :)
I could make a long list with such issues... If the price is the most important factor and you need basic cloud features and you are fine with a beta label GCP may work for you, otherwise you should look elsewhere.

Also a ton of third-party tools and documentation are built with aws support in mind.
