In addition to what you said, I feel that may be Google's view of a viable project (business-wise) is different from many others, hence any real drive to continue these POCs long term.

If we look at main projects/products at Google like Chrome, Search, Gmail, Android, YouTube, Maps, Kuberenetes none of them has any serious competitors out there (except for Android perhaps). I mean, sure we technologists are more aware of alternatives and open to try new things but almost every average user I know is utterly uninterested in an alternative. There's a perception of Google as simply being the most technologically capable company on the planet for average users and that any alternative simply can't match, let alone surpass, Google's offering. Sometimes, when I think about, there's some truth to the latter part of that sentiment. Google does a good job with the projects that actually last.

So, perhaps any project that can't have a similar traction in the market probably doesn't get a whole lot of attention on a collective level.

Chrome has competitors! It has majority market share, but other browsers get usage too.
