I think people should be responsible for the litter of their own tools. If their commits have include any litter it should be rejected as they clearly aren't paying attention. The local gitignore is for project specific files.
The fact that toil can be pushed off onto other people (the pushing and feedback and re-review also being additional time and effort) doesn’t change the fact that it’s toil and it’s stupid and wasteful.
No. Wrong take. Wrong location for obligation. This absolute collective toil argument would imply getting these into some kind of default baked into the tools, not something every new project should go out of their way to do something only for the benefit of everyone else but themselves. That is the pushed off work.
