Allow other modules add views object types and extend views ui ajax functionality

Problem/Motivation

I'm working on new module and would like to make it contrib.
The basic idea is injecting any peace of content (node, block, custom content) between views results.
It is easy to implement the injections itself, but it is hard to create UI embedded in views. I would like to use display plugin extender and place all configuration there. And again it is ok with the current functionality in views, but when I try to reuse functionality of different handlers like an area plugin - it is impossible, because all available object types are hardcoded in views_object_types function.

Proposed resolution

I prepared one small patch with altering views_object_types and views_ui_ajax_forms

drupal_alter('views_object_types', $retval);

and

drupal_alter('views_ui_ajax_forms', $forms); 

It would scientifically simplify my code of configuration UI for my module.
This is an example of using this changes:
