I think the second part of this sentence undermines the argument for `scoped` as a keyword: if *all* access levels are about scope, then *this* access level should not be called `scoped`, because the keyword should describe what's *different* about this access level.
That's not to say "scoped" is a bad name, but I think it's good because the space inside curly braces can be thought of as a "scope". So I'd revise this sentence to something like:
The scoped keyword is a good choice not only because the community has been calling this feature “scoped access control” all along, but also because a variable's scope is traditionally restrained to the curly-brace-delimited block the variable is declared in, and that's the behavior `scoped` implements.
