I see. You were pointing out the hyphenation or lack thereof? I think you might have missed that the earlier discussion was regarding "seated" versus "seeded". Thus your brevity made it looked like you were claiming that the "seeded" form was correct. I don't think anyone else was concerned about the hyphenation.

Now we have three variants in the wild. The correctly folded "deep-seated" and its harmless but slightly anomalous "deep seated". Worryingly, there's this new configuration "deep seeded" that a significant but unknown number of HN readers may have been exposed to. Although the original infection source has been neutralised, we must remain vigilant against sporadic recurrence in future.

Yes, I was indeed concerned by my wrongly perceived concern of whiddershins over the parent’s usage of the hyphen.
