--- Comment #1 from Dominic Cooney <dominicc@chromium.org> ---
The reason we check configurable and not just writable is so that we can
produce prototype whose constructor property is configured the same way Web IDL
specifies an Interface Prototype Object's constructor property is configured.

This is just for alignment with Web IDL. From the Chrome implementation
perspective, I think it would be technically feasible to relax this
requirement.

This could be done in Level 2 of the spec, since it would turn errors into
non-errors.
