Why is that? Is it kind of like the other project that was here recently, where it was created at FB but now independently maintained and not a corporate sponsored project (anymore)? Or is it deprecated and no longer recommended?

It usually means this is an experimental side project of some Google employee, and not an official part of any Google product strategy. Google likes for its employees' side projects to be released under Google's GitHub org, which you can variously interpret as good (Google wants to promote and support open source experimentation) or evil (Google wants to assert ownership of its employee's side projects) depending on how you feel about Google.

(I used to work at Google and had a lot of side projects. That was before Google moved everything to GitHub, but they liked for me to mark the code as copyright Google but "not an official Google product". I was fine with this arrangement.)

or evil (Google wants to assert ownership of its employee's side projects)

I believe these are still worked on company time, in which case it is absolutely normal for Google to claim ownership.

It means not currently an officially supported project. Most open source releases of internal code start out this way and may or may not become officially supported. It is different than deprecated, which was once supported but no longer.
