I'm working on a GitHub App and noticed that some of the enums in webhook payloads have a different capitalisation to the normal webhook payloads. This is pretty amazing since I assumed it would be the same code for both, but apparently not.

Either way, I think it would be a good idea to make enum parsing case insensitive to make the library more resilient to strange API implementations like this from GitHub's end.

I'm happy to do the implementation, just wanted to get a yes/no on the idea before I do the work.
