Different label based on new/changed/removed

I was wondering if it is either possible or desired to have a feature to: configure a label based on whether a file was newly created vs. a file was changed (vs. a file was removed).

In configuration I would imagine this could be written as follows:

"label on add":
  - on: added
  - example/**/*

"label on change":
  - on: modified
  - example/**/*

"label on remove":
  - on: removed
  - example/**/*

"label on multiple":
  - on:
    - added
    - modified
    - removed
  - example/**/*

"or if you don't care":
  - example/**/*

"and even": example/**/*

I have a working prototype at ericcornelissen/labeler (example PR added, example PR modified) which I could turn into a Pull Request for this project if there is more interest in this 😄

In practice I want to use this in simple-icons/simple-icons to label Pull Requests with either new icon or icon outdated based on whether a new icon was added or an icon was updated (respectively)

@SpencerKaiser and @ogtony, I opened a PR for this feature 👍

I would love to see this issue implemented because I’d like to remove the changes requested label whenever a commit is pushed to a PR I’ve reviewed.
