I will just pivot to a full offering for each nip-05 registrar I am making and incentivize it when it is used as primary with best in class offerings for all the features the competition is offering, with a discount for migration from other ones. Adding unique value on top of it.
Then it will not be an issue anymore.
Nip-39 is a way of listing non-nostr based identities on platforms that do not support nostr specific logic.
The idea that this is even a debate is telling in many ways. It very much seems to be a random hill to die on, until you look at the financial interest in all those who opposing it are running nip-05 registrars, but do not see the value in allowing an array of the same into the profile.
Nip-39 is far less implemented, user/dev friendly and its original intent seems to be for services that cannot provide a link to the npub.
For a project that is supposed to be about freedom and empowerment of the individual, there sure seem to be a lot of reasons to not do simple things that have demand and use cases.
It seems that we are also not the first to ask for similar and even when I pivoted from a new nip, to the suggested extension of nip-05, as requested, there is still a myriad of roadblocks put up by others who are selling nip-05 addresses and do not seem to want to enable any other potential entry into that space.
