GreenGrass V2 with ECC Keys in a Secure Element

How close is AWS in supporting pkcs11 ECC Keys in GreenGrass ? We are using ATECC608B's from microchip with AWS-IoT and that is already supported if we use our own mosquitto broker on the device, But for GreenGrass V2 this won't work currently.

I see some pull requests for pkcs11 keys (and an announcement here) and some for ECC so I assume it is on the Roadmap ? Is this a correct assumption ? And if so, is there a timeline that we can get ?
