If you are building products that intend to connect to a Google property moving forward you need to at minimum include the above Root Certificates. With that said even though we now operate our own roots, we may still choose to operate subordinate CAs under third-party operated roots.

For this reason if you are developing code intended to connect to a Google property, we still recommend you include a wide set of trustworthy roots. Google maintains a sample PEM file at (https://pki.goog/roots.pem) which is periodically updated to include the Google Trust Services owned and operated roots as well as other roots that may be necessary now, or in the future to communicate with and use Google Products and Services.
