How can I add a character count / column ruler to VS Code?

Question

All, I have been searching for a ruler similar to this for VS Code. I do not see an extension, and I am honestly not 100% on what this ruler is actually known as. It is used to quickly determine the number of characters in a line. I know that there is a read-out on the information panel that will display how many characters one has highlighted, but I like the ruler a lot better. Does anyone have an actual name for this device? Is anyone aware of an existing extension similar to this?

This was requested in Show column numbers in vscode #60537. It was closed as "out-of-scope" with the following message (emphasis added):

We closed this issue because we don't plan to address it in the foreseeable future. You can find more detailed information about our decision-making process here. If you disagree and feel that this issue is crucial: We are happy to listen and to reconsider.

Please be respectful and productive if you make comments there to explain why you'd like to see this feature implemented.

I'm pretty sure an extension couldn't add such a feature except maybe by doing some crazy wizardry with actual text in the editor buffer and something like the sticky line feature.
