Object values can be accepted into string Params - intended behavior?

[ckhordiasma]

Hello, I recently discovered that we can specify object values for string params - for example

# pipelinerun param
- name: colors
  value:
    red: apple
    yellow: banana

# pipeline param definition
  - name: colors
    default: ""
    description: Color mapping
    type: string

Any task that uses the colors param will get the object value serialized as a JSON string. This is a convenient thing to have but I saw no mention of it in the documentation. Is this intentional?
