 > The best way I can think of avoiding these kinds of conflicts is to add
 a short hash to filenames of intermediate image sizes to ensure that this
 is unique.

 How would such a hash be any better than the `-1`, `-2`, etc that
 [[https://developer.wordpress.org/reference/functions/wp_unique_filename/|wp_unique_filename()]]
 adds?

 [just seeking clarification, not criticizing the idea]
