Rewriting things in Rust is a reasonable thing to do. I think the hate is for people who criticize existing software for being written in C on the grounds that hypothetically someone could rewrite them in Rust.
"I rewrote SQLite in Rust" would be praiseworthy (assuming it's true). "Why don't you rewrite SQLite in Rust?" is trolling.
