I agree that other changes are necessary, but those are just in the brainstorming phase. So the community first has to agree on an approach, and then code has to be written and rolled out, which means it will take quite a while before we can have any advantage of those mechanisms. Increasing the reject fee can take effect right now, it does not require any code to be written.
While agree that this doesn’t fully remove the incentive to submit governance proposals, saying it doesn’t accomplish anything is in my view not a fair assessment either. Imagine that one individual submits bad proposals using ICP donations to pay for the reject cost. If the person gets 50 ICP donations, that would mean 50 bad proposals today and with this change it would only pay for 5 bad proposals. I think that’s an improvement.
