tsdown and unrun will ensure that the rolldown versions remain consistent before release, up until rolldown officially launches its stable version.

I understand, my point is that if I'm using .ts extensions in imports so that don't even need unrun, it's still installed anyway @sxzz

Here are the reasons why we currently keep unrun:
- Node.js 20 does not support importing TypeScript files directly, and it's unreasonable to require users to install additional tools manually.
- Importing TypeScript files requires an explicit
.tsfile extension if using native loader, and importing JSON files needswith { type: 'json' }, both of which are incompatible with the current Vite/Vitest config resolver. unrunis lightweight, and both tsdown and unrun rely on the Rolldown engine.- Previously, unconfig used jiti by default. Since Rolldown is already used in tsdown, its bundle size is larger than unrun.
