I can't speak for blogging usecases, but for agency websites we would disable revisions and a bunch of other things for every single wordpress installation(even the blog posts that show up on the main admin area)

Heck even Jetpack, Automattics official plugin, recommends limiting revisions: https://jetpack.com/blog/wordpress-revisions/

Lastly, Wpengine never fully disabled post revisions, they just limited it to 2-3.
