Wrong habitat config, could not be debugged easily

What's wrong?

When a wrong habitat config is provided using kubectl, it is not very clear if something has gone wrong.

Steps to reproduce

Built it from the current master: 14905ccf3af53eca2bc06ab9ef98646c84f75b8c

$ build-habitat-operator.sh                                                                                                                                                                                 
+ cd /home/hummer/go/src/github.com/habitat-sh/habitat-operator/cmd/habitat-operator
+ go install

and I have this habitat file

$ cat habitat.yml
apiVersion: habitat.sh/v1beta1
kind: Habitat
metadata:
  name: random
# this field could also be left out
spec:
  foo: bar

Which is an invalid file and I expect some errors, but I see no error while creating it:

$ kubectl create -f habitat.yml 
habitat.habitat.sh/random created

Steps to debug

No events reported at all, when checked using kubectl get events.

I see errors only where the operator is being run. The error being: msg="Habitat could not be synced, requeueing" err="unknown topology: " obj=default/random

Questions and suggestions

Is this the normal behavior? That I have to see logs of operator to figure out what is wrong?
Can we have a Status in the CRD? Which tells us state of the CR? Because looking at either of following does not tell anything:

$ kubectl get habitats.habitat.sh random -o yaml
apiVersion: habitat.sh/v1beta1
kind: Habitat
metadata:
  clusterName: ""
  creationTimestamp: 2018-08-13T12:29:30Z
  generation: 1
  name: random
  namespace: default
  resourceVersion: "261044"
  selfLink: /apis/habitat.sh/v1beta1/namespaces/default/habitats/random
  uid: 86f7a3df-9ef4-11e8-ba7d-080027cc5126
spec:
  foo: bar

$ kubectl get habitats.habitat.sh
NAME      CREATED AT
random    4m

Or should we error out when the config is being sent to via kubectl to server that the config is wrong?
