Not everything is about performance. Deno lets developers be more efficient than Rust, and it is easier to hire developers that already knows TypeScript/Node.

How is Deno more efficient?

If you're building a application on top of PostgreSQL and GraphQL then there's no Rust equivalent to PostGraphile, which is a JS/TS lib.

If you're building on top of GCP services, there are official JS/TS libs but no official Rust libs.

If you're doing data science then the ecosystem of Python libraries (another interpreted language) will get you up and running much faster than Rust.

So yes, there are plenty of cases where using an interpreted language will be much more productive than limiting yourself to Rust.

They mean more efficient for the developer not the machine.
