I think so too. Should be more rare.
There’s one in every system now. Would be better if they were less common…
… and if the rings had a few different colours: (red-orange dust, blue/white ice crystals, yellow/green toxic gasses, grey/brown ash…or whatever).
You could also have ‘anomoly’ rings, (when they appear around anomolous planets), filled with twinkling sparkly debris or purple crystals or something interesting.
