Nothing really, it completed its mission of a portable environment across SSJS, and saw quite some implementation effort. The commonjs module loading convention (but not necessarily the particular core modules such as for fs, http, etc.) became a standard for bundling in browsers even, before ECMA standardized ES modules, and their dynamic nature make them being used on Node.js until today, such as for expressjs. But around 2010, Node.js became the leading, then the only relevant SSJS platform.
