Node’s progress to modern stuff like ES modules has been glacial. Probably the primary reason Bun/Deno have any success. It is speeding up though, seems a fire was lit by competition.
It hardly matters on the enterprise space where projects live from LTS to LTS, and version upgrades only happen when someone allocates enough budget for a consultancy to come in and do some upgrade project.
These aren't the kind of folks rushing in to add Bun/Deno into their stacks.
