Are other providers (besides AWS) supported anymore?

Hello,
I’ve used the framework extensively for a while before v4 came out, and I recently wanted to use it again in a new project of mine but I couldn’t help but notice that the documentation refers to the AWS use case from the get-go:

Did the framework drop support for other providers? (e.g. GCP, Azure, Knative, etc.). My intention was to actually implement a new provider but it seems like that’s no longer possible, is that correct?

Thanks!

As of v4, no. AWS only.
