I've tried making the suggestion of a standard library several times and I would consider the reaction from the standards body to be "hostile," but then again I lost a lot of faith in TC39 when I took over the future of JavaScript's core infrastructure and they didn't lift a finger to encourage me or stop me or guide me. I don't think they have even noticed at all. Given that they simply won't engage with the biggest problems facing their community, it sure feels like they are passing the wheel to me to steer the ship.
