upgrading golang-google-api-dev: how much caution is needed?

[Drew Parsons]

The latest version of rclone requires golang-google-api-dev 0.28 [1].  
Current version is 0.21.

How sensitive is the go ecosystem to golang-google-api-dev version?
Should we take care to be careful, and upgrade in experimental first?

Or just push google-api 0.28 straight into unstable?
