Not sure if this was D14758 or another diff, but we definitely had an issue some time ago where the client was broken because the service was not released. I would create w task to coordinate services and client releases after this is landed

I did a staging deployment right after landing. Also, this change is fully backwards compatible and wouldn't break clients. The only consequence of not releasing it would be that supportsFarcasterDCs response would be always false, but it's not an issue since it's unused anywhere beyond development.
