Isnt this causing a systematic problem. I mean if the pool this error originated from now gains less trust, and the miners leave the pool due to lack of trust.

Now the pool can go bankrupt, and the other pools consolidate. Isnt this increase the risk of 51% attack? I think this is the main concern mostly.

As if the mining pools get sabogaged by these things, it can become very easy for 1 pool to gain monopoly and then face 51% attack?
