I'm not sure, I don't think so. Is this a PR card renewal milestone I should be on the look-out for?

Not that current processing timelines should be regarded as accurate predictions for the future. I imagine that there is a glut of PR renewals right now from post-OB407 RQ recipients and others caught in the record citizenship delays. I would not be surprised if the PR card timeline continued to lengthen.
