Yes, it's been that way for about as long as bash has had local variables.
The idea is that variables are readonly for a reason, and you shouldn't
just be able to circumvent that with a local variable declaration. It's
similar to the error you get if you try to assign a value to a readonly
variable using an assignment statement that precedes a command.
