They're too expensive to put up with that kind of damage. I had some very minor damage to a rear corner of one the the T8's I got a few weeks ago. But it is hidden when assembled and not structural so I didn't really care. But what you've got would bother me. APC is a bit on the slow side as well so that'll be frustrating. Ali will probably just send you another piece though so you could assemble it anyway and change it out when the new one comes.
