It is surprising for me to see these features finally being added to Node after such a long time. Especially so when I remember reading discussion after discussion about how something like this wasn't possible. I touched on this in a blog post some time ago [1]. Glad Node is catching up.

I don't see in your blogpost any sources cited regarding anyone saying that ES modules were infeasible.

Additionally, io.js actually forked off due to internal drama which started with Ben Noordhuis having changed some pronouns here and there and people wanting to cancel him for that, to which he picked up his toys and left the sandbox.

It so happened that aside from being competent himself, he had competent people on his side, which eventually forced those governing Node.js to concede.

Bun is just a cash grab in comparison.
