The public facing API / types should remain identical with this change, so I reckon we can do this as 1.1.3. On our internal benchmark project, this drops type instantations from about 1.59 million to 1.28-ish. I expect at least 555k to be non-farstorm related, as replacing InputType and OutputType with any drops to that number. This is with a bunch of typing errors on account of narrowing to never not working properly, so definitely could be higher in practice.
That's all measured with tsgo 7.x, not the 5.x tsc tool.
