The "too late" argument isn't gonna fly with someone like me who has both the time and energy to own a Javascript runtime. Heck, I'm quickly becoming the most prolific author of the ES spec too.
From what I'm reading, it's too late for Bun. I hear the whole dev stream is slop now. It was nice while it lasted, but that's not a foundation to build rock-solid stuff on top of. Not for me, not for them, not for anyone.
