It's not a big deal, although I'd have liked to see the hole a bit more centered.

For bending, the stresses on the structure is at the highest at the edges. At the center there's virtually no stress, a principle highly exploited in lattice girders.

And since a bike fork is almost only expected to see fore-aft bending, that may well still be strong enough.

The design might make the fork fail a bit earlier during (accidental) exposure to sideways loads.
But the ability to continue riding AFTER an event severe enough to throw you to the ground isn't a safety issue.
