No Gutenberg - Disable Gutenberg Blocks Editor and FSE Global Styles

No, I don't. I think that is more important to decide what you want in your WordPress and what not. If you don't want to make this huge step to the new Gutenberg Editor with this plugin you'll have de decision in your hands.

• You'll recover the brand new Gutenberg Editor
• Your life will be a little more difficult from that moment :)

This plugin is compatible with all WordPress JavaScript functions (wp_localize_script(), js in header, in footer...) and works with all well coded plugins and themes. If a plugin or a theme is not properly enqueuing scripts, your site may not work. If your host doesn’t support any of the tweaks, usually due to security restrictions, is possible that something fails. If anything fails please access to your /wp-content/plugins/no-gutenberg/ directory via your favourite FTP client or hosting panel (cPanel, Plesk, etc.) and rename the plugin folder to deactivate it.

Nope. I'll expect Matt and all the rest of this beauty guys to abandon the idea that a blocks editor is a good idea for post editing.
