If a Wiki post is editable by non-staff, shouldn't there be an option to allow those who can edit the post to see all the edits to it?

Plugins: ad manager and data explorer
No theme components
I think it was last updated on Sunday.

I tried to install a theme component recently and it failed with internal error 500.

Safe mode doesn’t seem to change this, nor does unsetting the ‘edits are visible to all’ flag and creating another post turned wiki.
