In the last year they've deprecated 14+ services/features and they've been really bad. They will email existing customers but they won't announce it publicly to avoid the bad press. Documentation pages are updated quietly with banners or removed.

Recently, I attended an hour long meetup from a high-level AWS employee about CI pipelines using CodeCommit. Of several possible deprecation announcements, the latest of those was dated the day of the talk. (!!)

In all fairness to the speaker, except for having one of the most prominent icons across his slide deck deprecated in real time, it would have been a pretty decent talk. He even made an effort to promote the GitHub integrations as a path forward, and provide some guidance on current tooling. It was clear CodeCommit wasn't the path of most momentum, even if the degree was unclear.
