Will it have all the features of a Yubikey? I have two YubiKeys right now. One with NFC and one USB-C. I would love to just have one, and open source is a plus. I also use the NFC one for 2FA code storage. I then can use my laptop or phone to retrieve a code.

Not at the beginning. We're starting FIDO2/U2F only, but we'll have the possibility to upgrade the firmware. PGP/SSH are the top feature requests, TOTP we'll have to look into it, if the way yubikeys are doing it is open, we're happy to be compatible.
