Comment (by ironprogrammer):

 Following @manfcarlo's train of thought, adding the `edit_posts`
 capability to the `wp_navigation` post type registration ''does'' enforce
 the restricted access that is expected on the Navigation Menus edit page.
 It is no longer accessible by non-admins. That addition could be added to
 @noisysocks's PR.

 **Related Issue**
 While I believe it to be separate, this is worth mentioning here, as it
 will come up during testing, whether or not the above adjustments make it
 into this patch.

 The following issues were observed when when accessing the block editor as
 a non-admin (tested: editor and author).

 - Without the fix applied, in both 5.9 and trunk, non-admins have the
 ability to add, edit, and remove Navigation blocks. I don't believe this
 is by design (there are several "toast" warnings to this effect).
 - With the fix applied, when a Navigation block is present, its block may
 be replaced with the warning: ''Navigation menu has been deleted or is
 unavailable. __Create a new menu?__'' Clicking "Create a new menu?" allows
 some basic tinkering with the Navigation block (e.g. alignment, colors,
 styles), which can be saved. After saving by a non-admin, the block
 appears as a "placeholder", but with styling applied.

 I'm trying to track down if this has been recorded in Gutenberg issues,
 where I'll post additional details.
