In my tests, the D-rings themselves break at about 45 kg or 99 pounds load (on average), and the attachment point itself should be stronger than that, but over time things could wear. If I were you, I’d probably use it as-is but keep an eye on it and if it looks like distributing the load over one or two more points would help, then it looks like you have room for some Type-2 attachment points in front and beside that one.
