The question of full site editing, header, and footer contemplating and in particular universal-style settings I can easily see us getting away from the motto of Decisions, not Choices. I know those in the meeting are carefully considering this but I have some concern about the compounding effect of some of those choices.

From my experience with the block editor, what makes the editor compelling and potential a joy to work with is when a theme and theme author do a good job building out and styling both the default blocks and custom blocks ( I think, as we see in tools like ACF or many page builders, custom blocks will remain an important aspect of the block editor experience at least for more complex or custom themes. You don't want to be building out complex sections out of several default blocks ). The pages become easy and enjoyable to build out when you can quickly start adding fully styled blocks reusable templates to quickly build out the structure of the page. Then on top of that, you have some simple preset style variations that allow you to quickly adjust how those blocks are laid out.

That's the editor experience that I am trying to find in the block editor at least. That's what makes me excited about it.

When it comes to building out more options and granular control, something closer to a page builder plugin like experience, plugin authors have shown that they are more than capable of filling that need.
