I find it really difficult to understand the thinking here. Nostr privkeys are both nostr keys and git keys. But the argument I want to use them only as nostr keys, rather than use them both nostr keys and git keys, I cannot see as a technical argument. I just cant see it. It's like having the number "2" and saying, we can use that to add, but not to multiply. It's a thought process that I find alien, and see no way past it.
