| ## Scope | ||
|
|
||
| This replacement is for **existing `tsup` users** only. It is not a recommendation for projects on other bundlers, or for projects that do not need a bundler. |

we may not need to specify this, as it could do the reverse of what you intended - it could make it sound like we recommend against using it for other projects.
i'd probably just drop the scope section and hope the title is clear enough that this is specific to tsup.
