The TypeScript syntax is very stable - there is no spec, but it's very stable. The type system on the other hand: not very stable, and yeah I agree - that would be risky to rely on.

However as JSR only relies on the syntax, not on the type system, it's no problem :)

Is not the 'slow types' problem[0] a type system dependency, or am I missing something?

It does not use TSC / do type analysis. This is purely syntax analysis.

The "slow types" restriction specifically exists because JSR does not use TSC or do type analysis :)

Ah, I see
