I just want to mention that this is far from a "slight hassle". We
managed to screw up the swap partition for many cycles -- as soon as
you enabled "encrypt my home dir" (which is rather popular) or
manually partitioned on LVM, we either left the system with a
disfunctional swap (i. e. wasting lots of space but not using it) or
with an unencrypted swap (thereby leaking data from encrypted

See LP #1453738, #1447282, and the really infamous #953875 for
example. These are all fixed now, but the fact that this went
unnoticed for so many years is perhaps telling that swap partitions
are not that important any more :-)
