It's easier for you to get a new NIP than for any normal dev to even get a small change to an existing NIP. So, changes to NIPs don't seem like a big deal to you, whereas NIPs are basically carved in stone, from the viewpoint of most other devs.

It's not easier for me. I propose so much crazy stuff that people just ignore my NIPs these days... "There comes Vitor again". I found that it's easier if I just convince somebody new to send the NIP than sending it myself. Reviews are softer because everybody welcomes a new person. Less biases. In that way, I can also see if people are liking it because of the idea or just because it's coming from Amethyst and will be implemented anyway. I do appreciate the criticism over the idea itself.
