End names are optional in Ada, so "fixing" that is just a style guide away. Meanwhile, Scala 3 added named `end` to help with long blocks on its indentation syntax.
Like in all such discussions: the problem isn't with what you write, but with what you read. There are tons of Ada code that's already written like that. So, future changes to the style guide aren't going to do much. Also, nobody's changing that anyways.
