Focus on ESNext

Many libraries that work with different versions of JS have the ESNext option, which means the latest version of ECMAScript that is released or available in the library. Example Perhaps it is worth focusing not on any particular version of ECMAScript, like 5 or 6, but on ESNext (strict mode), as those libraries do. Support for the new syntax will appear in new versions. Outdated syntax will cause errors or warnings. There will be a compatibility table of library versions with ECMAScript versions.

Perhaps the ECMA themselves will support this, they almost do not need to do anything for this. And you can call it Ecma Object Notation (EON) or something like that. By the way, there is already such a package, but it has been abandoned.
