Is it fundamentally possible to create a custom area through Customizer that would allow adding Gutenberg blocks. Similar to a widget area but one that can be managed through Customizer panes and allow for Gutenberg blocks instead of widgets.
The user case I am thinking of is have the ability to add CTA buttons, and icon links to the site navbar area within a custom theme. I am aware I can ad a new sidebar and add widgets to it which would render in my navbar, however I hate the contextual disconnect of adding a "sidebar" that is not an actual sidebar. More importantly I want to be able to leverage our design system elements that will already be available as Gutenberg blocks.
As compromise I have added a simple input field in my Customizer settings that I can ad shortcodes to that will render using the do_shortcode function in my header template file, however I have yet to find a intuitive way to make Gutenberg blocks available as shortcodes.
