False advertisement on unsupported languages in GH ("Code 55% faster with GitHub Copilot")

I mainly work with languages such as Purescript, Rust, Clojure and Nix, so I feel it is false advertisement when I see "Code 55% faster with GitHub Copilot" on files that are written in languages that are not even on the list of supported languages for GitHub Copilot.
Feel free to write that statement on top of files in languages for which there is actually official support, otherwise its just misleading and false marketing.
I was almost considering to try out copilot, but luckily I decided to read over the list of supported languages first, and decided not to try it because I don't work with any of the supported languages. Not everyone might read through that list, and they might take the statement for granted ("Code 55% faster with GitHub Copilot") since it is literally written on top of the file they are working on -even if that language is not supported.
