One said such a ring couldn't form, being outside the Roche limit. (And got it wrong.)

It did form. Did the object's mass change, so the RL moved?

Did gravity pull the ring into an orbit, and the ring's extended but our instruments didn't grog that it's sort of a small-scale equivalent of a protoplanetary disk? Did the minor planets just have enough gravity to attract the dust and ice granules?

Intriguing. Interesting.

But sometimes two similar things have two different origins. Not Occam's-friendly, but sometimes the outlier is an "entity" that needs to be dealt with.
