Bug Report Checklist

• I have tried restarting my IDE and the issue persists.
• I have pulled the latest main branch of the repository.
• I have searched for related issues and found none that matched my issue.

Overview

This comes up once in a while. Contributors sometimes ask to add files like .DS_STORE, .idea, Session.vim, etc. to .gitignores. I generally ask not to because:

1. The fewer lines of config in a file / in a repo overall, the easier it is for folks to understand the repo
2. There is a practically unbounded set of stuff folks want to .gitignore
3. If I start allowing one type of stuff -e.g. editor configs- then that set will grow over time
4. Therefore, I'm just ... not into having any non-essential .gitignore files

In other words: my goal with .gitignore, as with other configs, is to make it as small as possible.
