The reason I don't softraid1 my swaps is that the default behavior is
striping a-la-raid0 if you have multiple swaps. At least that's my
understanding of it.

You guys bring up a good point in case of drive failure. I never
tested it. Do you guys know what happens if the swaps are not
softraid1? Does the kernel panic or something of the like? Or does it
survive and just operate on less swapspace?
