If anything their one engine out unexpected but successful test boosts their position a bit.

Blowing up on the pad is incredibly worse from a design data collection perspective, a risk to life perspective, and a downstream impact to future launches perspective (nobody can use that site for a couple of months).

The entire point of SpaceX’s recent launch was an explosion. They were aiming for that outcome. They wanted that outcome.

The fact they did it with pinpoint accuracy even with engine issues and an in tact heat shield is a monumental success for a test flight.
