I would say that you're not necessarily being lazy there, if you configure a 
swap partition then you are limiting where the kernel can write bytes on the 
SD card which will lead to uneven wear on it.

In future with a COW SSD aware wear-leveling filsystem like btrfs a swap file 
may end up being more SD friendly as the filesystem may (hopefully!) balance 
out those writes across the card.
