I guess it's mostly for interpreted languages. Try installing (not that I use it) Eclipse the Java IDE as another example, it's usually dated enough. This is probably why people use bleeding edge distributions. I guess in the case of compilers it's not as bad, though you can't usually get the latest and greatest Go compiler either, you have to grab the .deb off the website or use other tools. At least Rust just hands you rustup so I don't need to worry about this in the case of Rust, but with other languages like Python it's a concern of mine.
