You Want How Many Years Experience?

Right, so did I, and people were using it in production in 2015, but the first release was in late 2016 so you were using a testing version or used it late in the year. So this site rounded down from a little over 2 years from the first release. I imagine many of these dates would change depending on how you're defining when the technology first existed. And I remember how there was a sentiment that Google should just officially release the thing and there were worries about how the project might just be limping along and that could discourage one from adopting it if the project was going to be abandoned. But if the original commenter was just saying you could get an early version of it more than 2 years ago then it doesn't seem like that interesting of a comment and it doesn't justify the tone.
