You can just add it in a user-level gitignore instead of ignoring it in every repo. See: ~/.config/git/ignore

This has the disadvantage though, that this user level gitignore file will not be in the repo, which means that other less careful contributors have to fix ignoribg for themselves.

I only realized very recently that being able to specify .gitignore files in any part of a repo can be combined with wildcards to just put `.gitignore` with `*` in a arbitrary directories to make them get ignored without needing to modify any wider configuration.

yes, but user level is not a repo level

		Yes, but this is exactly the sort of thing that should be a user-level configuration. A personal scratch directory has nothing to do with the repository itself and doesn’t belong in a repo’s .gitignore. If it's only needed for one particular checkout, .git/info/exclude is the other obvious option.
