Indeed. I only read the blog post, where this info is missing. Thank you.
If I understand correctly, then Cloudflare's paradigm is: We have a bunch of polished, simple standard services and if you want to do something slightly different and/or do something on the network you can use Workers. I think it's pretty smart and empowering as it strikes a nice balance between great, simple DX and high flexibility.
Most of their new products are also built on Workers. Most of them were already possible before, just with more manual work.
