I think Google is getting blowback from the "worse is better" crowd that have supported the meteroic rise of c, php and mongodb. Specifically, the "worse is better" belief that:
"There is a point where less functionality ('worse') is a preferable option ('better') in terms of practicality and usability." [2]
reminds me of his criticism of "excessive" features in Angular, even though those features are there for a reason.
Usually, what happens with "worse is better" is that when people start missing key features, a bunch of bolt on pre and post processor tools show up to add features (e.g linters, "strict mode",Mongo migration tools) that weren't needed in the more complete solution.
