There's benefits to be had for the average developer from being able to easily read the compiler/jit/vm code of their language.
I write Crystal code and the fact that the Crystal compiler is written in Crystal allows me to make my code better/faster by taking a peak into the compiler code occasionally to see how things are done without having to get good at another language.
