Babel doesn't have a spec per se. They try to be compliant with the ECMAScript spec, but implement popular proposals behind presets or plugins. You can read about their relationship to ECMAScript and the TC39 committee on their blog: https://babeljs.io/blog/2018/08/27/7.0.0#babels-role.
Norway puts their oil revenue into a fund, and puts the surplus of this fund into their yearly budget (the rule is to use less than 3% of the current value of the fund). This amounts to about 20% of the budget I believe.
Getting something through the TC39 is a pretty lengthy process, you can read about it here https://tc39.es/process-document/.
