What problem does this feature solve?

Hi 👋 I'm currently working on a module to improve DX for nuxt, its main goal is to help devs with hydration.

Currently, when a hydration mismatch happens, we don't really have any idea of why it is happening (except having a string logged in console).

What i'd like to do is to have a hook that can be triggered with informations about what went wrong, the parentComponent , the vnode and DOM element could be provided.

What does the proposed API look like?

I think a onHydrationMismatch() function that could be a __DEV__ only hook would be nice to have.

Or

just being able to customize the handleMismatch() function of createHydrationFunctions()
