A lot of non-accessibility apps use the accessibility features to do things like window resizing and clipboard management. Looking at my relatively pristine MacBook Pro's settings, I've got Flycut and Rectangle (expected) and less expectedly Dropbox and Aquamacs with accessibility access.
I think (but could be wrong) that it's a relatively low-risk permission to grant.
