if early_request_filter can return Result<bool>,just like request_filter?

[Withsan]

i just want do publish an endpoint to help downstream client do some "health check". so i left this to early_request_filter ,but when i write response to downstrem，downstream_module still receive request.(because those modules do auth etc). so if we can let early_request_filter return Result,when we return false,request will stop here
