Comment (by SergeyBiryukov):

 [attachment:21240.5.diff] is another take.

 * As far as I can see, there's no need for `no_items` label to be based on
 `menu_name` (this wouldn't be localizable). It can fall back to "No Tags"
 / "No Categories", like the other labels.
 * We should probably keep the existing `$posts_columns` keys and CSS
 classes for categories and tags for backwards compatibility.
 * A separate `taxonomy_column()` method doesn't seem necessary. We could
 just combine the cases in `single_row()`.
 * I think the taxonomy columns should be added before the comments and
 date columns.
 * `$posts_columns` filters should be applied after the taxonomy columns
 are added, not before.
 * `__( $taxonomy_object->label )` is not localizable.
 * `taxonomy_column_header` filter doesn't seem necessary, we can add it
 later if needed.
 * `taxonomy_column_args` filter doesn't seem necessary as well.
 * Some minor edits as per the coding standards.
