Seems like this is a move to remove alpinejs from the custom block elements in tailwindcss plus? I don't see alpinejs in the code snippets anymore.
edit:
Confirmed, they removed alpine from their copy/pastable code. Now you see:
<!-- Include this script tag or install `@tailwindplus/elements` via npm: -->
<!-- <script src="https://cdn.jsdelivr.net/npm/@tailwindplus/elements@1" type="module"></script> -->
This sucks because I have been using alpine and now I can't copy paste the examples ~_~
