Even if you don't want to use the space for swap, there are still things you
use the extra space for. For example as back up space that is more convenient
to recover from than tape or DVDs or whatever.
You can also do some things for testing OS upgrades if you keep your OS on
a different mirrored partition than your data. You can split the mirror for
a while testing if the new version is good enough and then put it back
together when you have decided whether or not to go forward.
