Forumlar / Cotonti / Core Labs / Ideas / Anket: Plugins and Modules merge (again)

If we are planning for the future are more differences between the modules and plug-in that division should be. For example plug-in performs some system functions: connects JS, performs some validations, plugins executes from hooks. Ie plug-in complements the core or other modules. In this case, combining them would not be correct. I am a supporter of such a path.
The modules in this case are the individual pages (like pages, forum, users)
In this case, in the future it will be easier to build a new admin panel uncluttered.

If between the modules and plug-in makes no difference - then merge. Duplication of code - it is bad.

Sorry for my English :)
