Sorry, but I have to disagree for now. Core blocks are basic to say the least.

Let's start with the column block. It has not semantic element settings. So pretty much from the first block on the page, your site is not Accessible and you need a more complete section block from a plugin.

Mobile responsive settings for core blocks: NOPE! ehh are you serious WP.

Then what about dynamic content. There is a latest posts block. What about for other content types. Really a product like toolset should be redundant, not essential.
