What problem does this feature solve?

Seems like the instruction on how to type ComponentCustomProperties and ComponentCustomOptions aren't covered by the TS integration page of Vue3 docs.

I could find some examples into the TSDocs of the related interfaces.

https://github.com/vuejs/vue-next/blob/11a76ebd94932d04a54c8c60e60121ecf13c35a9/packages/runtime-core/src/componentPublicInstance.ts#L66

This problem has been raised here but apparently ignored or misunderstood.

What does the proposed API look like?

Adding a section about global plugin usage as there where in Vue2 docs

Can you open an issue or pull request in the vuejs/docs-next repository?

Sure, didn't know there were a separate repo
