Abstraction can be performed at many layers, and not all of them lead to 
performance problems. For example, custom fields could be implemented in 
such a way that the table structure changes every time a new field is 
added/removed, and we could have a couple of conversion scripts between 
those table structure.

There are a lot of ways to reach the 3.0 goals and not all of them have 
performance problems, although some are uglier/complicated compared to 
others. The trick is to found the balance between performance, 
abstractization and beauty of the code :)
