Comment (by poena):

 Hi again.

 What about function _add_default_theme_supports() which enables HTML5
 script for block themes by default?
 https://github.com/WordPress/wordpress-develop/blob/trunk/src/wp-
 includes/theme.php#L4386

 (I didn't remember this existed until I started looking at the Docs issue)
