Now that circuit breaker and load balanced pool is in GA, it would be cool to see this in azurerm too.

Any updates here? Is it going to be implemented on the provider?

Bumping this thread because I'd love to see this feature supported in Terraform once it's out of GA. I recommend using the azapi provider in the meantime, I've had a lot of success using it for load balanced pools and custom metrics in my APIM applications.

Bumping please. Would be so much nicer to do it natively than using azapi. Thank you
