What should I replace it with? Any recommendations for a functionally equivalent cross-device 2FA app?
What does 2FAS give, genuinely curious in case I'm missing something..

Others have also said Bitwarden isn't too bad: https://bitwarden.com/
Seconded. The jerk maintainer needs to cut a release though. And maybe port it to something other than bash.
(Seriously though, thank you, it's been incredibly useful so far!)
Why would I store my second authentication factor alongside the first? Aren't we effectively now back to 1FA?
Adding TOTP on top of that helps guard a bit more against some kinds of attacks. You can make it even stronger by not storing those keys in the same place and only using your phone, for example, but for some people (myself included) it's one bit too inconvenient. The good thing about using TOTP for 2FA is that you can find your own balance between convenience and security.
