It's the only one there. The current crew will be using it to return to earth at some point. The manufacturing defect is in a portion of the spacecraft that is jettisoned before reentry anyway.

The hole is drilled in the orbital compartment of the Soyuz, not in the landing capsule. If you don't forget your spacesuit - which you shouldn't forget anyway - you're reasonably safe.

"reasonably safe"

To be reasonably safe in space is a rather good measure... I do see your point though.
