There were no error made in this coin but now there is an initiative to make some changes. Changes are always bad and changes destroy participant confidence even in case these changes are looking as useful. We have to be very careful before making any changes in coins

Also, miners aren't the only stakeholders, and while a miner voting process is great, it isn't the answer to every question. Though I do agree that miners need to be on board with any hard fork to avoid a harmful split.
This is the point. The network that isn't supported by miners is useless. We have to ask them.
