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.
Yes I agree with that, as I said. To be fair though, I believe that a large portion of the current hash rate, most likely a clear majority, was active in the meeting where these things were discussed.
I agree. Let's make two separate voting processes.
Merged mining will be turned on only in case 75% of hashpower will be supporting it. For me this is ok. If less we will not introduce it. Is this ok?
For emission schedule modification is 75% a good margin?
