Do git commit hooks work for you? You and your collaborators can do whatever. The hook ensures things are converted to either tabs or spaces prior to commit. You can also set up a CI job to auto-reject any PRs that aren't tab/space compliant. This is all pretty pretty straightforward to configure on a per-repo basis too, so you can hop around multiple projects with different standards and not have to think too much about this.
