You do need it for hibernation support, it's true.

For 20Y I have recommended 2× physical RAM as swap space, but now we
have PCs with 4-8GB of RAM becoming commonplace and 12-16GB not all
that rare, I think 2× RAM is too much. If you want hibernation
support, I'd probably allocate RAM+2GB now. If you have more than 2G
of stuff in swap, your system will be on its knees anyway, I think...
