We use [highlight.js](https://highlightjs.org/) for our codeblocks, and I don’t believe they support line numbers… there’s some rationale in their documentation here: [Line numbers — highlight.js 11.9.0 documentation](https://highlightjs.readthedocs.io/en/latest/line-numbers.html)

They can definitely be useful for reference, e.g., “you can change the font size on line 3”… so if we’re ever looking to move away from highlight.js, that would be one thing to consider.
