no one thats been following the test campaign for Super Heavy is surprised by the damage. the damage to the pad has been documented after the 3, 14, and 33 engine Static fires in the run up to launch. I believe they said SpaceX has been experimenting with different concrete formulations in the repairs after each static fire. There has also been photos of what appears to be flame diverters on site at Starbase, and I think they have even done a crude test fit of them under the OLM at some point recently.
