There's a "dedicated thread" on the question here https://github.com/nodejs/loaders/issues/214 https://github.com/nodejs/loaders/issues/214 There are about 100 messages in the comments on the linked PR all about the import extensions compatibility/consequences :) There's a "roadmap doc" here https://github.com/nodejs/loaders/issues/217 https://github.com/nodejs/loaders/issues/217 that states "No .js extension for .ts files." > I'd prefer it break existing code to enforce correctness That seems to be the goal and intent (from TS and Node team too https://github.com/nodejs/node/pull/53725#issuecomment-2230113189 https://github.com/nodejs/node/pull/53725#issuecomment-22301... ) > Will it transform esm import syntax into require statements?
