 > adding custom columns in edit-terms.php screen forces Screen options to
 show in term.php.

 Hi @szaqal21 - This is happening because `edit-tags.php` and `term.php`
 have the same screen ID. When you add columns to the screen (in this case,
 `edit-category`, or whatever the taxonomy is), they're displayed on both
 of these pages.

 The behavior appears to date from [36874]. See #34988.

 I don't think it's intended behavior. Screen Options shouldn't show up if
 the only thing it's going to show is checkboxes for a list table that
 doesn't exist. I don't know whether the right solution is to give
 `term.php` a different screen ID, or to do some sort of trick on
 `term.php` to ignore or unset any custom columns added via filters like
 `manage_edit-category_columns`. @swissspidy - what do you think?
