I see; I suppose it would certainly help though, to be able to patch bugs out before they actually come to the live server

It wouldn't really help a ton, because they still need to send to Korea for a fix. The only advantage is that if it's found in Tespia, they can send for a fix earlier but as far as what we've seen either they ignore most reports because of the sheer volume they obtain or Korea asks them to see if the problem persists into the live server before fixing.
