Passing though/inheriting slots

[hagabaka]

Sometimes you want to have a component to pass all its slot content to its only child, similar to what inheritAttrs does with attributes. As far as I've found, ways to do this in Vue 3 are quite unwieldy and hard to remember:

<template v-for="(_, name) in $slots" v-slot:[name]="slotProps">
  <slot v-if="slotProps" :name="name" v-bind="slotProps" />
  <slot v-else :name="name" />
</template>

What's the reason for slots being inherited not being the default behavior, like with inheritAttrs? Is it possible to have an option to allow a component to opt in to inheriting slots? And is it possible to provide a way to easily pass slot contents to one of multiple child components, as a counterpart to v-bind="$attrs"?
