I can see this as design and/or manufacturing flaw depending on circumstances.

IF at some point the problem of copper lands detaching from the PCB surface was corrected, that's a manufacturing issue. The connectors are not likely to break free from the copper where they are soldered.

However, I am still convinced the best overall solution, especially to be on the safe side, would be to go to a through-hole mount. That eases the onus on manufacturing process and widens the tolerance band.
