Hello API Owners, This feature was launched on Desktop in Chrome 136 and Android in 142, and we unfortunately forgot to request Intent to Ship approvals. I just realized this mistake while we were cleaning up old feature flags, my apologies. Are there any concerns or could we please have retroactive LGTMs?
For context, this was an additional feature to WebAuthn that had an already existing spec and an implementation in WebKit. Several large Relying Parties have adopted it already.
