Short answer, no. Different design, similar plumbing. We encrypt your existing key behind the passkey flow, so the nsec stays your identity. Nosskey looks like a new signing approach where the passkey itself becomes the key. Our goal was something familiar that just works. That said, it looks like a good option, and I could add it as a complementary signing method if people want it. Keys can also move between the two today by exporting the nsec.
