I'm also voting to remove the best-practices tag as all answers should adhere to the WordPress Coding Standards and/or best practices in general.

It's silly that some people still give bad advice and/or bad answers (with bad practices) like for example this debate: How to add crossorigin and integrity to wp_register_style? (Font Awesome 5) Luckily they get downvoted and the answers with adhering to WordPress Coding Standards and/or best practices will always stand out and voted up.

That's a short example of why we don't need this tag, as people expect answers with best practices.

Tag is unnecessary
