As to whether or not I want it tracked/versioned, that is completely outside the workflow for versioning in code in a repo. You can maintain a "version" of this separately ala Wikipedia's edit history, or even just have a hidden separate git repo for these things if you must use git. They already have this with gists.
With lint configs or npm configs you can argue that changes to those would affect code, which would require them to remain in sync. But what is the point of this new issue_template.md as part of the git repo? It's not as though there will be any significant time where a code change necessitates a change in how issue templates are made.
This feels like a bad hack. Like they saw CONTRIBUTING.md and thought, "well might as well just keep going" and added issue/pr templates.
