CodeIgniter 2.0 - A defense of plugins

[eluser]Crimp[/eluser]
I'll clarify:

When I refer to an internal cache, I talk specifically about HTMLPurifier to exemplify that some of today's plugins are far removed from the helpers. It is obviously not practical, and utterly pointless, to start caching its deifnitions elsewhere because with such a plugin you, well, plug and play. Those are the key words.

This organizational aspect of development with CI seems to have been forgotten in the process of cleaning up the folder hierarchy.
