This twitter reply sums it up well:

“SUCCESS! We now now max pressure the tank can hold and the damage a rupture might do.”

[lmilcin]

Well, we know max pressure THAT PARTICULAR TANK could hold.

Don't get too excited about the damage, in space it does not matter much, the crew is screwed anyway.

[taneq]

Good news, everyone!

Ah so this wasn't an accident? They needed to know the pressure limits so they purposely blew the bulkhead?

[CydeWeys]

Unlikely.

But they have learned to be more careful with the welds going forward. Though, admittedly, they only used panel welding on the first prototype and have already switched it up for the second one.

It clearly was an accident, why would they put 3 rocket engines in it if they were going to stress test the tank?
