As a user of GCP it reads as a huge red flag to me that they offloaded this instead of rolling it into GCP.

Domains are a pretty core part of cloud infrastructure. The fact that they could have brought domains under GCP and didn’t makes me wonder what they know about the future of GCP that isn’t public yet.

GCP has Cloud Domains. It's unclear to me what the future of that is.

Well…that’s even more damning. Why did they not just roll this into cloud domains?

Perhaps they have different audiences? I guess if your on GCP, you wouldn’t need to use a non-GCP domain product.

There isn't one.
