@OlgaMaciaszek this enhancement should by moved to 4.0.0-RC1? Asking because 4.0.0-M5 was already closed but this issue still open

Comment From: OlgaMaciaszek

Yes, I've moved it.

Hello @OlgaMaciaszek, this improvement ended up being left out of RC-1, it would be great to have this point implemented together with the first release of cloud 2022, is this the planning or is the idea that this support will come in future versions?

@lgklein I am working on it now. The plan is to have it done before our GA release.

is it means we can use this feature by the end of this year? @OlgaMaciaszek

@HakChealKim The plan is for it to be ready with the 2022.x Spring Cloud release train, which is scheduled for mid-December. We're currently working on it.
