I'm ok with it for now. As others have said, let's see how it plays out. I do think it would not be terribly hard to modify it in the way I highlighted below in red (bottom photo) if they find the hard sharp angle more dangerous than envisioned. The way I drew it in the lower image, the wall would be similar to the Fenway right-center field angle. I counted the seats from the O's ticket page and it would span 34 seats to get from the corner to the end of section 84. The upper photo shows that it could join about where the workers are applying the padding. Curiously the O's ticket page still shows the old dimensions, but the seats that are gone are grayed out (unavailable).
If they went this route, I'm guessing the wall would be about 390 where the guy on the ladder is and it decreases until it reached the 376 of the bullpen angle. It's 398 with the current reconfiguration in that last section before the bullpen.
