They definitely just wanted to A.) Play with Rust, B.) Write a post about it.

This is the key line:

It's fine to say "I rewrote this code in Rust because I like Rust". We don't have to do a whole song and dance about why X needed a rewrite in Rust because X wasn't doing a good enough job. People do exactly this work in Node every day successfully. They just wanted to write Rust instead of optimizing some Javascript. _Which is fine_, just totally not newsworthy.
