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)
"Every WP Engine site has WordPress revisions disabled by default... Revisions can only be enabled by contacting Support... Support can help you enable 3 revisions for your posts to start. Revisions should not exceed 5."
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.
