Overlay with `update: []` doesn't actually update the spec

Given spec.yaml:

openapi: 3.1.0
info:
  title: "..."
  description: "..."
  version: 1.0.0

servers:
  - url: https://example.com
    description: Super secret, don't share!

And overlay.yaml:

overlay: 1.0.0
info:
  title: "..."
  version: 1.0.0
actions:
  - target: $.servers
    update: []

When running:

npx bump-cli@2.9.11 overlay spec.yaml overlay.yaml

the resulting spec is:

openapi: 3.1.0
info:
  title: ...
  description: ...
  version: 1.0.0
servers:
  - url: 'https://example.com'
    description: 'Super secret, don''t share!'

However, I would expect it to have replaced the servers with an empty array

That being said, testing it with i.e. https://overlay.speakeasy.com/ shows that Speakeasy also don't seem to do the same, so maybe I'm misinterpreting the spec?

I assume that instead using remove: true is the best option
