Gonna have to sorta disagree with you, @
Tcoat.
I know its a fringe case, but both my old FRS and new BRZ have had 6-puck clutches and they will absolutely embarrass the driver on a hill start. There is no way short of launching the car to get it to get moving easily on a steep-ish hill and as such, I use the e-brake. Now, 95% of the time, I do it the normal way, but I can't say that there is never a time where the e-brake is necessitated.
But as far as OP's question goes, you should be able to handle just moving off with the clutch in most cases. Especially with the very forgiving stock clutch.
