AWS/GCP/Azure are full of abandonware. I’m more familiar with the AWS-side of things, and most of them were/are built on top of existing core services. AWS’s/GCP’s image is fine. I’d say as long as CF’s core (CDN/DDoS mitigation/etc.) is stable, they should experiment.

To put it this way, it took GH almost a year to release Stacked PRs to public. And it’s already being questioned if it’ll stand the test of time. Again, insanely competitive market, as everyone wants to sell shovels.
