I do think we should allow HTML attributes to be set for attributes_table_for but no defaults, especially not for the id attribute which needs to be unique. The reason you can't set an id attribute for attributes_table_for is the method fallbacks to using the *attrs argument for the table rows as yet another shorthand default. I'm not sure that's a good one but not really interested in changing it. I would be open to a PR to accept HTML options (kwargs/hash) for that component though if it were possible. Otherwise, you can wrap your attributes_table_for in a div id: '...' block to set your id and then link to the admin show page (e.g. admin_item_path(item, anchor: 'custom-title')) with that anchor.
