They'd save themselves a lot of hassle if the actually issued people who qualified with long term visas. People try to game the system because of its largely absurd in nature. I remember back in 2001 working with a guy who had a daughter with Thai nationaltiy but struggled to stay here. Things are worse than 2001 and I don't see them getting any better. Married for decades and still renewing visas every year, the mark of an absurd system.
