Main parts of the CAPTCHA 8.x-1.x module seem to be a port of the Drupal 7 CAPTCHA module, with quite similar implementation.
But since Drupal 8 form styling and overriding was improved a lot by using twig files for form elements where ever possible. Trying to reduce the need for hooks to theme Drupal forms (as it's bad for theme developers / designers).
Having a look at the resulting markup and the implementation, CAPTCHA didn't improve a lot here. The resulting markup, which is also used by CAPTCHA extending modules like
and other CAPTCHA types using hook_captcha() can also be improved.
In this task we should discuss two things:
1. How to better use twig files to replace the need for hooks and technical FAPI implementations for theming the CAPTCHA generate output
2. How to improve the currenct CAPTCHA output markup like for example:

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Just a small reminder, as I couldn't remember, why 2.x is D10 only.
The reason behind this is, that besides the type hinting introduced in the newest Symfony release, used for D10, there were also method implementation changes (See https://git.drupalcode.org/project/captcha/-/merge_requests/47/diffs#1f6...).
That's why the newest release is D10 only! 👍
