And it doesn't matter that play was discontinued? That to me is different to just not entering a score for some holes.
It is indeed different. If you miss out some holes in a Stableford round you are not discontinuing play which the Rules do not allow but simply omitting the holes which the Rules (in the Decision cited above) do allow. If the holes you omit are the final ones - whether just the 18th or the 10th to the 18th - that is no different from the missing holes being the 8th or the 15th to 17th or whatever.
Discontinuing play (legitimately or otherwise) means stopping play when you are required to keep on playing. If you choose to omit the 18th in a Stableford, you are entitled to do so i.e. there is no requirement to play it.
You will not find any justification in the Rules for disqualifying the player who played only holes 1-9. That was the realisation I came to which showed I had been mistaken in arguing for a DQ.
