Personally I rather like that convention (and similarly for Go). Often I will follow links that specify one of these two languages since I primarily work in Go and Rust, and it's useful to add them to my mental map (or favourites folder) of what is available such that if I need something similar I can find it again. Libraries or tools written in C++ interest me less personally, because they're more work for me to integrate into whatever I'm typically doing, but I can see that someone working in C++ might like such things to be labelled the same way for the same end.
