Thanks for the PR! It looks like you've changed the TSServer protocol in some way. Please ensure that any changes here don't break consumers of the current TSServer API. For some extra review, we'll ping @sheetalkamat, @mjbvz, and @joj for you. Feel free to loop in other consumers/maintainers if necessary.

Looks like you're introducing a change to the public API surface area. If this includes breaking changes, please document them on our wiki's API Breaking Changes page.

Also, please make sure @DanielRosenwasser and @RyanCavanaugh are aware of the changes, just as a heads up.

Can we please get this reviewed? I know the country is burning and everyone is being replaced by AI but this would be really useful for those of us who deal with audiences across different languages.

We have a lot of these lib related PRs; it's absolutely our intention to review all of them as soon as we can, we've just had a bunch of other stuff that has been a bit more pressing.

I will note that an all-up PR for this may not be as useful as us reviewing the individual esnext PRs and then having a dedicated ES2025 PR; them being mixed together in this PR is making it hard to figure out what's new and what's just moving around. I would have preferred that the other PRs not be closed and this PR be a pure move + define options.
