IPhone :: Movable Safari Tabs On IOS Devices

While using my iPhone today I realized that there does not seem to be a way to move the position of tabs within safari.

I had 6 tabs open, and just based off of intuition, I tried to move a tab's location by pressing/holding onto one thinking that it would eventually shake and become movable. I was surprised to see that nothing happened and that there did not seem to be any way to rearrange tabs in safari on an iPhone (and I would assume iPad as well, but I cannot test that until later tonight).

What do you guys think about the possibility of adding the functionality to press/hold onto a tab in safari to have it shake and become movable. I think it follows the "you already know how to use it before you use it" mentality and would would be used by many users, especially if this functionality is not already on the iPad.
