Meta plans globe-spanning sub-sea internet cable

> We are also deploying first-of-its-kind routing, maximizing the cable laid in deep water — at depths up to 7,000 meters — and using enhanced burial techniques in high-risk fault areas, such as shallow waters near the coast, to avoid damage from ship anchors and other hazards.

How does this affect maintenance? Is it still possible to pull portions of this cable up to repair it? What happens when it is at end of life? Does it get removed?
