To me "craft" is about keeping code efficient, scalable, extensible, well-tested and documented. Code style is more about what naming convention to use, tabs vs spaces etc. - it's nice to have it consistent, but no need to spend more than 5 minutes arguing about it.
Tabs/spaces is a non-issue, agreed - IDEs handle it.
But surely naming convention contributes to keeping code documented, extensible and efficient?
A deviation from the norm leads to people thinking x does not exist in a large code base, leading to them implementing duplicate methods/functionality, leading to one instance evolving differently enough to cause subtle bugs but not enough to be distinct, or leading to one instance getting fixes the other does not etc?
Sample size of 1, but I've seen it happen unfortunately.
