I used that a few years ago because I wanted to use my U2F Fido token to use for ssh login on my routers as well and dropbear does not support ed25519-sk keys. But since that was a manual installation, I had to redo it after every firmware update, so eventually I gave up and used a non-sk key like everyone else... my luck, I guess! 😅
