More concretely, given that pruning nodes keep at least the last 288 blocks, it would require a reorg of over two days.

I wonder how many users run pruned nodes at the absolute minimum. I checked the default suggested pruning size again

I believe floppy's article (and my summary of it) could have benefited from a clear statement that this requires a reorg of depth greater than pruning. Likely though this is mostly caused by my misunderstanding of his article.

Right, it would likely need to be even deeper to affect nodes, but the reorg would need to be at least 288 blocks.

Likely though this is mostly caused by my misunderstanding of his article.

I only skimmed the article, but I don’t think it made that point clearly before the recent amendment: #1514882
