Comment:

 This seems like a good feature to me. A few comments on
 [28232-alternate.diff]:

 * `sprintf( __( 'Filter by %s' ), $taxonomy->labels->singular_name )` is
 not properly localizable, because of the way many languages will decline
 the taxonomy name. If we want the screen-reader-text to match that of the
 Category dropdown, then we'll need a new taxonomy label - something like
 'filter_by_item'. @SergeyBiryukov does this seem right to you?
 * We should pass `'hide_if_empty' => true` to `wp_dropdown_categories()` -
 taxonomies with no terms should not have dropdowns here.
 * Let's use booleans instead of integers when building the
 `wp_dropdown_categories()` argument array. (Never mind that the Category
 dropdown does it the other way.)
 * Not all taxonomies will have a non-false `query_var`, and I don't think
 we need to depend on the existence of `query_var` to make this feature
 work. I recommend doing something like this: if the taxonomy has a non-
 boolean `query_var`, use it; otherwise use `sanitize_title_with_dashes(
 $taxonomy->name )`
 * We need better escaping (`esc_attr()`) in the `<label>` element.
 * Why bother getting the 'objects' from `get_object_taxonomies()` and
 filtering down to 'name' on the next line, only to call `get_taxonomy()`
 in the `foreach` loop? I'd suggest removing the fourth param (`'name'`) in
 `wp_filter_object_list()`.
