As mentioned in the CL description, I believe the draft's behaviour

I haven't done any research to verify if that difference could break
applications or not, but it might be good to answer those questions here.
Also as noted, this does not modify the runtime concat routine which
appears
to
be carefully optimized for previously spec'd behaviour.
There are still some issues with the subclassed-array behaviour that is
mandated. Maybe a good place to figure that out
Frankly, not sure we want to lead the way for other implementation in this
particular case :)
Risks seem great for not much benefit. Maybe we should go back to TC39 with
this.
