Related: #9788

As of #9788, we now surface a "Manage All Reusable Blocks" link to post listing of reusable block types more prominently. The primary use case here (one assumes) is for importing, exporting, or deleting reusable blocks. However, when clicking into the detail page for one of these reusable blocks, the user may be left confused as there is nothing for them to edit or preview in the main column of the single reusable block editor. This is technically to be expected because the wp_block type does not have the editor supports.

Proposal: Should we consider adding editor and/or title support for the reusable block type? Or at least present the user with some preview of the block? Or an explanation as to why they should not expect to see any content in the main column of the editor? Should we add additional labels to avoid defaults such as "Edit Post"?

The main problem seems to be that the original implementation of reusable blocks was made as if they were not intended to be exposed through traditional default scaffolded UI for editing.
