Comment (by jonsurrell):

 Given how little `html5` `script` support is apparently used outside of
 Core, I'm tempted to leave the behaviors of `get_theme_support()` and
 `current_theme_supports()` unchanged. [https://github.com/WordPress
 /wordpress-develop/pull/10919#issuecomment-3896349183 I've described some
 of the difficulties I discovered on the linked PR].

 This ticket can then close with some documentation that `html5` `script`
 theme support is deprecated.
