> No, this was intentional decision.

> [snip]
>
> Reflect isn't a "class", it is just namespace defined using an ordinary object.
> Such name space objects are now widely used in JS code and typically don't have
> custom toString behavior. So we followed the precedent of ECMA-402 Intl and did
> not give Reflect its own @@toStringTag
>
> Part of the motivation, was a desire during ES6 that we should minimize the
> specialness of builtins. In general, we wanted built-ins to be as much as
> possible just ordinary objects that might be implemented by everyday JS
> programmers and hence the builtins should generally follow the same
> conventions as we expect ordinary JS programmers to follow. For the
> class-like buildins we established a new convention of using @@toString on
> the prototype to name class instances. Hopefully that is a convention that
> will catch on with JS programmers. For namespace objects like Reflect we
> expect JS programmers to continue to use direct object instance (often
> constructed via object literals) and that they typically won't give them
> unique @@toStringTag properties. So most name spaces including Intl and
> Reflect will print as "[object Object]".
