ManagedApp on macOS 27: can an ACME-provisioned identity be hardware-bound + attested

Hey guys, I'm building a managed macOS app (credential-provider extension) that needs an MDM-provisioned, hardware-bound, attested identity via the ManagedApp framework on macOS 27 which just released days ago, and I've hit a documentation contradiction.

By reading through the docs, my understanding of the ManagedApp identity path is com.apple.configuration.app.managed → Identities → com.apple.asset.credential.acme.

But the OS27 ACME schema says, for both HardwareBound and Attest: "On macOS, this is a required key. Set the value to false" (https://github.com/apple/device-management/blob/seed_OS_27_0/declarative/declarations/assets/credentials/acme.yaml#L66) — implying a software key. However, the macOS 27 release notes say ManagedApp deploys "hardware-bound identities" on macOS.

So I am wondering that on macOS 27 + Apple silicon, can a ManagedApp-provisioned ACME identity actually be HardwareBound: true / Attest: true? If yes, is the acme.yaml "set to false on macOS" text just stale? If no, how is the documented "hardware-bound identities" capability delivered? And would that identity gonna be able to be used by the app / app extension? Thanks!
