We haven't been here for years and we haven't been part of those discussions. If you want to change the NIP-01 spec, let's go ahead and change it. Someone arriving later shouldn't have to guess where something is headed. You're expecting us to fork off a spec that doesn't yet exist.
Liminal was assuming that NIP-01 contained the expected standard and tried to fit his stuff to that, which was very reasonable.
We can submit a PR for NIP-01, as well.
