[1.76.1] EC2 Metadata Credentials change?

After spending the last 24 hours trying to figure out why my jenkins ci/cd pipelines have failed, it appears that in the most recent (1.76.*) support for EC2 Metadata Credentials has been removed from sls.

Was this intentional?

If not, will it be reinstated?

If so, what’s the new best practice for setting these credentials?
