The main reason to split your servo power into a separated BEC is redundancy.
Especially with bigger/faster servo's, the power the servo requires might be too much for the 5V regulator incorporated into the ESC. If you overload the ESC regulator it will shut down, taking out power to your servo's, receiver, etc.. you will loose control when that happens.
A separated BEC will ensure you have receiver and servo power, even if your ESC overheats and shuts down.

If you don't live on the edge, you take up too much space.
