This point stings for me, personally, since _I_ was the TypeScript language dev _in_ this wg trying to make our concerns noted, because we certainly did participate. However the group largely deadlocked on shipping with ecosystem compatibility measures, and what you see in node today is the "minimal core" the group could "agree" on (or be bullied into by group politic - this was getting shipped weather we liked it or not, as the last holdouts). The group was dissolved shortly after shipping it, making said "minimal core" the whole thing (which was the stated goal of some engineers who have since ascended to node maintainer status and are now the primary module system maintainers), with the concerns about existing ecosystem interoperability brought up left almost completely unaddressed. It's been a massive "I told yo so" moment (since a concern with shipping the "minimal core" was that they would never be addressed), but it's not like that helps anyone.
Like this shipped, because _in theory_, it'd be a non-breaking from a library author perspective to get node's CJS to behave reasonably with ESM (...like it does in `bun`, or any one of the bundler-like environments available like `tsx` or `webpack` or `esbuild`), and _in theory_ they're open to a PR for a fix... I wish anyone who tries good luck in getting such a change merged.
