 > What about function _add_default_theme_supports() which enables HTML5
 script for block themes by default?

 Good question. There are a few places `script` and `style` are still used
 with `html5` theme support. [https://github.com/WordPress/wordpress-
 develop/blob/a479b0a42c06dfe14f377fe4579206a1650ccc8f/src/wp-
 includes/theme.php#L4399 _add_default_theme_supports() is one], and
 [https://github.com/WordPress/wordpress-
 develop/blob/a479b0a42c06dfe14f377fe4579206a1650ccc8f/src/wp-
 includes/theme.php#L4261-L4283 the REST API is another].

 Effectively, theme support for `html5` `script` and `style` is always
 enabled. [https://github.com/WordPress/wordpress-
 develop/pull/10919#issuecomment-3896349183 Actually implementing changes
 to reflect that seems to be more trouble than its worth.]

 I considered removing these from the REST API and default theme supports,
 but it's harmless to leave them. Removing them is potentially disruptive
 for extenders. I don't think there was ever much reason for themes or
 plugins to ''check'' for this theme support, but it's possible.

 I plan to publish a dev note for 7.0. The remaining `script` and `style`
 can be considered for removal in a future version.
