The problems occurred during an engine relight. Missions to the ISS do not require this. So in the worst case it would be pretty low risk to launch an empty Crew Dragon to the ISS.
This looks like a manufacturing problem rather than a design fault, there have been over 340 Merlin 1D Vacuum engines without this problem and several thousand Merlin 1D engines (9 x M1Ds per flight) without this fault.
I would guess they will spend more time dealing with FAA reporting requirements than doing the root cause analysis.
