 > Can you give more details about what breaks? Are you getting some sort
 of error? Here is the relevant unit test:

 When there's no meta values to delete, then this function returns a value
 which is `==false`. It should return a `==true` value.

 So the relevant unit test would be something like:

 public function test_bp_xprofile_delete_meta_when_no_meta() {
   $this->assertTrue( bp_xprofile_delete_meta( 0x7FFFFFFF, 'field' ) );

 > These are highly targeted substring replacements that are covered by
 extensive unit tests.

 I'm sorry, but I don't understand how they're highly targeted. Both
 Wordpress and Buddypress are very extensible programs - the both have many
 hooks that allow plugins or themes to modify their behavior. And that's
 why they're so popular. But this causes that there can be no "highly
 targeted substring replacements", as relevant strings are moving targets.

 Please consider the following example. A function
 bp_xprofile_update_meta(), as I understand, should be used to add
 additional meta values to xprofile fields. This is used by my plugin to
 add two strings, controlled from dashboard, to any xprofile field.

 But these string can very much contain for example a substring "WHERE ".
 Like a message "PLEASE GO SOMEWHERE ELSE". Trying to save this string as a
 meta value would generate SQL error:
 ''WordPress database error: [You have an error in your SQL syntax; check
 the manual that corresponds to your MySQL server version for the right
 syntax to use near 'field' AND ELSE' WHERE object_type = 'field' AND
 `object_id` = '24' AND `meta_ke' at line 1]
 UPDATE `wp_bp_xprofile_meta` SET `meta_value` = 'PLEASE GO SOMEWHERE
 object_type = 'field' AND ELSE' WHERE object_type = 'field' AND
 `object_id` = '24' AND `meta_key` = 'validate_with_regex_error_message' ''

 And all this so Wordpress functions like `update_meta` could be used on
 different table than `wp_postmeta` or `wp_usermeta`. When simply using
 `$wpdb->insert()` and `$wpdb->update()` would be much, much simpler and
