Upcoming Lambda API change: Lambda States Lifecycle for VPC functions

On the 20th AWS will make changes to how Lambdas deployed to VPC’s operate. https://aws.amazon.com/blogs/compute/coming-soon-updated-lambda-states-lifecycle-for-vpc-networking/

How will this affect Terraform users?

My CI/CD pipeline runs a set of tests on our API Gateway as soon as Terraform returns. Does that mean these tests will fail? Does Terraform currently wait until the Lambda is “Active” before returning or just waits until its “Created”.
