I am guessing two possibilities: 1. The friction to onboard new users would be pretty high as it currently stands, if they have to go and figure out using a key extension. 2. The developer, in this case @hodlbod, would need to trust that the signing extension options are excellent, and have been audited rigorously. I can imagine that as a developer, if one knows one is acting in good faith, it might be easier to trust oneself and one’s intentions, than those of others? Curious to hear thoughts, esp from developers @ hodlbod @jb55 @Vitor Pamplona @miljan @Martti Malmi @Kieran @brugeman
