Quarkus @Singleton reactive subresource and its locator.

[AK1HIKO]

I have a subresource CurrentUserResource.java:

@Singleton
public class CurrentUserResource {
    @GET
    @PermitAll
    public Uni<String> test(){
        return Uni.createFrom().item("TEST");
    }
}

And I have a UsersResource.java, where I want to register CurrentUserResource as a subresource for path "/v1/users/me":

@Path("/v1/users")
public class UsersResource {

    @POST
    @RolesAllowed({User.Role.ADMIN})
    public Uni<User> create(CreateRequest req){
        //...
    }

    @Inject
    CurrentUserResource currentUserResource;

    @Path("/me")    // Subresource locator
    public Uni<CurrentUserResource> userSubResource(){
        return Uni.createFrom().item(currentUserResource);
    }

}

I am wondering:

1. Is it a good idea to define a reactive subresource as @Singleton and later inject it? My motivation for injection was that without it, by simply returning new CurrentUserResource(), CDI was not aware of it, and I could not inject anything inside (for example, @Inject JsonWebToken jwt; inside CurrentUserResource kept returning null)
2. Is it correct to return Uni<...subresource...>? I tried simply public CurrentUserResource userSubResource(){...}, however DEV UI kept saying that the "/v1/users/me" "Relies on a blocking worker thread".
