keep empty objects when converting yaml to props

[devopsmash]

I have the this yaml file foo.yaml with the following content:

a:
  aa: "foo"
  ab: {}
  ac: 123
  ad: []

When I'm trying to convert it to props it seems that yq ignores empty objects/lists.

Example:

yq -o=props foo.yaml
a.aa = foo
a.ac = 123

expected results:

yq -o=props foo.yaml
a.aa = foo
a.ab = ""
a.ac = 123
a.ad = ""

Is it something acceptable and achievable?
