How many languages go through the first 11 years of life without significant changes? There are lisps, which have no syntax to change, and I guess elixir, which is itself just a syntax for a very mature runtime (BEAM). Hell, even C underwent pretty major changes from 72 onwards, because every compiler supported entirely different features. Things like void functions and returning structs or unions. Granted, this predated internet distribution of software, so changes overall were perhaps slower within a single implementation, but there were still radical developments happening on a frequent basis.
