Installing plugin to fix the core?

It now takes way more time for my SEO team to add and change content on pages and posts.
Installing the classic editor plugin works but as a developer it feels very wrong to install a plugin to fix the terrible mistakes of the core.
Also, looking at the amount of code that is required to revert this gutenberg stuff back to something normal is crazy.

I just can’t believe that there are so many other “WordPress developers” that build this and thought it is actually a good idea to have it like this, even with this amount of bad reviews.

As many others said. There shouldn’t be a plugin to fix this. It should be a core functionality to choose between the mistake and the normal editor.
