The captcha.settings description has no limit as a text string in configuration, but the CAPTCHA settings form prevents input greater than 256 characters. It is then possible to import a longer description, but then lose that description if a user saves the form.
We should avoid data loss. Either the settings should also be constricted to 256 characters or a different form element is used to allow for longer text strings. I think that there is not a reason to limit the number of characters in the description.
This is probably a holdover from Drupal 7 variables.

Change the "Description" field from a text field to a text area so that it is easier to write text that may exceed the input box (even 256 characters makes it difficult to write). Potentially also change the "Wrong CAPTCHA response error message" field to a text area as well. Remove the max length property on both fields.
- Merge request and any test fixes.
The Captcha settings form Description and Wrong CAPTCHA response error message fields are changed to text areas and allow longer input.
No.
No. CAPTCHA already supports longer description and error strings.

I went ahead with a merge request that changes both to text areas.
