You just made me realize why I've always considered 'chore' the most ambiguous type. In addition to being loosely defined ("transparent change with zero functionnal impact"?), this one is indeed a word related to emotion. No wonder it has a more subjective meaning than 'fix' or 'feat'.

This is why I never use it and almost always pick 'feat' to please the linter. Because I can't help considering that any change worth committing is improving the quality of the code in one way or the other, and thus a feature.
