- Recursive directory tab completion isn't viable for many key use cases (it'll hang with both monorepos and networked volumes). The only thing that makes zoxide viable is that it only matches against visited directories. (Similarly fzf doesn't have much of a relation here besides encouraging recursive fuzzy matching, which I tend to avoid because it doesn't scale to complex directory structures.)

- Zoxide is probably sponsored by Warp, I doubt they have a relation beyond that, I'm not sure but they don't have much of a synergy beyond both being written in Rust. (The main point of relevance here is Warp is venture funded.)

- Zoxide having a database outside of the shell is actually a huge advantage to me, because it makes it easy to access your database outside of the shell (e.g., Zoxide integration in Vim).
