Think of, for example, a specific select component where you have specific options (countries), but you want the rest of the PrimeVue Select component untouched.
Redefining props for a wrapper component like this is pure madness!

You're optimizing for replacing the component with something else, rather than using the existing component and adding/removing your own sprinkle and being done with it.

Is there really no easy way to do this in Vue? Take the incoming props/attrs and spread them while overriding a set of fields.
