ALB, NLB, EC2, and ELB Built-In Metrics

[ASE]

We are in the process up upgrading deprecated "built-in" Classic metrics to Cloud Services metrics.

Are there any plans to deprecate the ALB, NLB, EC2, and ELB Built-In Metrics and allow us the ability to add the Cloud Services metrics for each of theses to our environment?

If yes, do you have an ETA as to when?

Thank you.
