In reply to Joseph.

“This seems like a great example of the disconnect between how WordPress core imagines WordPress is used in the wild versus how many—typically agencies—actually use it.”

This! In my experience, while browsing the trac and the Gutenberg repo, I’ve noticed that no, or almost no, core devs do client-based work. Therefore, they are not familiar with typical WordPress use cases in business environments like the one you describe. And this poses a significant issue since they are neglecting a substantial portion of the WordPress community.
