I absolutely despise when people commit their personal ignore patterns. My opinion is that the code in the repository shouldn't know anything about personal environments. The exception is when the entire team benefits from having their common ignore patterns in the repo - in this scenario, the environment details are no longer personal and it doesn't make much sense to not commit them. In any other situation, people are perfectly capable of ignoring their crap on their own and shouldn't pollute the repo. Glad .git/info/exclude is getting more exposure.

Beyond things not being neatly compartmentalized, what is the problem? The only risk I see is that you'll have a file you forgot to commit because it happened to match one of those patterns.

Having strong opinions on stuff like this is not healthy.

It depends on whether the pattern is general enough to potentially be useful for others. If it is, then by all means add it to .gitignore. If on the other hand it's specific to the user, e.g. '2026_report.docx', then no, it should not be added.
