I very seldom, if ever, see a "Show HN" title with a suffix of "written in Java" or "written in python" or "written in Go".

"Written in Rust" seems to be a very popular thing to add.

My assumption is that people know it will get the thread more visibility?

The signal works both ways. "Written in Java" would save a lot of clicks. So the Java author may omit the label for the same reason. /s
