I was thinking along the same lines but didn't know if you wanted to change things.
I would consider plugins what you refer to as extensions now cause they plugin to the running code.
On a side note, or why I dislike Windows:
Decided to try out the Luna Element 4 theme, I just use the classic theme in XP. Downloaded it, ran the exe and installed it. Fired up Display Properties, selected it and everything went black except some icons. I spent the last hour trying to get my user account back to the classic theme. Thankfully I kept the Owner account around and created a new account for myself when I got this new laptop, so I kept switching users to determine what keys to hit in the darkness.
Oh how I miss plain /etc text config files
