Ed25519 SSH public key support

**When will CodeCommit make ed25519 available? **

I use CodeCommit's ssh credentials in Iam to link EC2 (Linux) users with IAM users.
I found the speed of ed25519 to be great, so I considered switching to ed25519, but the CodeCommit ssh credentials in Iam didn't support uploading in ed25519 format.
Supporting ed25519 will reduce the load on the AWS side and improve the user experience by the connection speed factory. However, this issue does not seem to have been addressed for a long time.
When will this event be resolved?
