Action items for standard:

• Survey implementations to ensure we have enough (3+) and/or encourage more implementations to support this feature.
• Write documentation
• Updates to GEP, docs, and API types to bump status to standard.

[keithmattix]

Implementations: Istio, Envoy Gateway,? Is anyone aware of more?

[youngnick]

Cilium also supports labels and annotations in infrastructure.

[jbohanon]

Gloo Gateway supports attaching implementation-specific config to a Gateway via annotation with the intention of moving the attachment to infrastructure once the GEP is accepted and the field is considered stable.

[keithmattix]

I think the only tasks left before this gets closed out is to bump some API types

[youngnick]

Yes, we will need to remove the experimental tags from the infrastructure field and the child labels and annotations fields, and check that we document the required feature name in those fields. Those actions will move this field to GA in 1.2.
