You must be really fun at parties man..

Think of this as the start of building in Gutenberg, for a fact I guess the Yoast team is rewriting a lot of their code to make it word with ALL the different blocks instead of just 1 content area and some (custom) meta fields.
For a fact, I certainly know the Yoast team will make something good from it. Since they are te first (and only?) big SEO tool that actually IS integrating with the Gutenberg editor.
