I think you are lobbying the wrong person about the relationship between yaml and json; I was trying to point out that you had

  thing:
  - item1
  - {{ foo | toJson }} # <-- is not going to do what you expect

unless you quite literally wanted

  thing:
  - alpha
  - - alpha1
    - alpha2

Ah, I did have a typo. But you also copied it wrong. I wrote this

    labels:
        - mylabel
        - {{ extraLabels | indent 4 }} # toJson doesn't work here.

Which has an extra `-` and as you pointed out would produce a nested list.

But I meant this which would merge the lists.

    labels:
        - mylabel
        {{ extraLabels | indent 4 }} # toJson doesn't work here.
