In my opinion, it is the sharp edge that is the biggest threat to the integrity of the cover.
My biggest concern would be that the razor sharp edge will slice the cover to shreds.
I would then refer any response from the cover company regarding the edge to my pool builder. What that would get me is probably not much but I would do my best to push blame to the pool builder.If the cover gets sliced into ribbons, the manufacturer will probably not cover it under warranty since the edge is so sharp.
See what the manufacturer says.
