Just so we're clear, this was more or less a joke! As far as I'm concerned, lnav is just fine as it is. There's no urgent need to rewrite it.

Why I wrote the comment: I saw the headline, checked out the website, and thought to myself, “Hey, cool—a new handy tool.” As is typical for “cool new and handy tools,” these are usually written in Rust these days ;) That’s why I was “disappointed” (not really).

I didn’t realize until later that lnav was created in 2007.

Again: the tool is great, thanks and kudos to tstack for the work.
