Those are good points. Regarding an appeal, the caveat is that I do a lot of appellate work but never in the Virginia State courts or applying Virginia zoning law so anything I say is wide open for rejection. The legal analysis in the decision seems careful and thorough. The fact issues regarding publication and what the newspaper did and when seem to have been undisputed. The ruling that three plaintiffs had not waived their challenge is based on highly specific credibility rulings by the trial judge. In most jurisdictions those are a basis for reversal only in extreme cases. The time required to decide an appeal is, as you suggest, a factor. I have no idea what a customary timeline is in Virginia but appeals often take a year and more to decide.
IIRC, the rezoning decision was issued by a lame duck board on its way out the door. If the appeal fails and the developers try again, I suspect there will still be opposition but who knows what will happen.
All that said, for now it ain't happening. Good.
