Adding additional information to tap output

[smyth64]

In my tap output I get this:

# test › Make test
not ok 22 - test › Make test
  ---
    name: AssertionError
    assertion: assert
    operator: '!!'
    values:
      'Value is not truthy:': 'false'
    at: |-
      assert (test/services/test/test.js:47:7)
      t (test/services/test.js:40:14)
  ...

But what I want is additional information that I can parse later to a JSON.
I tried it with test.log() but it always prefixes an asterisk (*) so the default tap-parser ignores it =/

# test › Make test
not ok 22 - test › Make test
  * ---
  * lala: lolo
  * ...
  ---
    name: AssertionError
    assertion: assert
    operator: '!!'
    values:
      'Value is not truthy:': 'false'
    at: |-
      assert (test/services/test/test.js:47:7)
      t (test/services/test.js:40:14)
  ...

Is it impossible to add just some payload to the tap output? This is so inflexible...

What kind of additional information?

What kind of additional information?

For example IDs or data that's generated while testing. I test an external service and I want to add the logs of the output to my tap output.
