You're already using a new runtime with tsgo -- it's golang at build time -- but still running Node in prod, so the same could work here. :-)

Agreed I would not want all Typescript users forced to use /this/ runtime, but if the TS team shipped tsc as "oh now it's uses a special fast JS runtime" (just like tsgo is a different runtime) I'd love to at least have the option of using the same special fast runtime in my own still-written-in-TS apps.

Seems I've either struck or a nerve, or miscommunicated, given the insta down votes.
