Show information about block usage, so a user can make an informed decision about hiding blocks

[ntsekouras]

There are some requests for showing information about block usage, so a user can make an informed decision about hiding blocks. This information could live in the block manager or even somewhere else in the editor UI.

This has been discussed a bit here: https://github.com/WordPress/gutenberg/issues/28572, until this comment: https://github.com/WordPress/gutenberg/issues/28572#issuecomment-772498512 (so read more about it by scrolling up :) ).

Related discussions should be made here and not in the tracking ticket for block manager to be grouped better.

Follow on to conversation from 28572. Understanding how often and where a block (or a reusable block) are used has similar value to the existing tools that let you do this with categories and tags. A simple use case. A custom block was used because of limits in a core block. A later release addresses this limitation and you want to understand and plan the replacement work. Eddy Simms Find My Blocks plugin and Jean-Baptists Audus Reusable Blocks Extended both address aspects of this.

It's interesting how we almost come full circle. A different kind of block manager was spart of the designs for the Block Directory. Secretly hoped then, that it would go forward for the block editor.

Thank you to @ryelle for reminding me today in a conversation on the #core-editor Slack channel
