Steve Yegge, a former Googler & GCP Customer begs to differ. From my experience GCP does deprecate a lot of libraries, SDKs, and APIs. None of which are covered in the SLA policy.
You might want to work somewhere else so you hear some differing opinions, pretty much nobody I know wants to implement on top of google products including GCP because of the perceived churn.
What were you using it for? I'll be upfront in saying that my experience with GCP was awful, but I can appreciate that others found it useful and would be curious to learn more.
