In reply to Niki.

Only static components that do not require editing. Take for example the Header / Footer of a page, those never change, hence, require no standard user adjustability. The context is changeable but the component itself, isn't.

I used to work directly with Flexible Content within ACF Pro but now transitioned to ACF Custom Blocks due to their native nature of integration on to WP. I would like to see something native from WP that either replaces this process or aids it.
