I am currently migrating in a REAL 2.5 MVC !!!
If you check your MVC, you can see it is old school way of doing.
This is good news to hear as Joomla 2.5 has integrated many new goodies in their MVC. I just think on this new way of handling forms by using Jforms.
Also some users already mentioned it: Jdom is certainly a good concept, but it is just too different from standard Joomla. It might be a good thing to have a choice of using either Jdom or the standard Joomla way.
