You don't have to remove it, after you press "remove" it will tell you what other packages will be removed along with it.
These packages are the ones that depend on it. Its just a way for you to see what other package you have that needs this Springboardaccess.
You can then back out of the removal process, no need to "confirm", just hit "cancel"
Btw, who told you it's for restarting springboard, did you read the package info.
It says its a mobilesubstrate extension that allows to control status bar icons....etc
EDiT: sorry, did not want to come across as rude
