The primary reason for multiple partition is that the partition can take
different mount options. E.g., if a stable Debian system you can put most
directories in a read-only partition, which probably deny 90% of the
attempts to make a back-door in your system. Or, you might want to disallow
SUID scripts from /tmp and /home directories. These things need a separated
partition.
If you don't need all these, then it is best to have a single partition,
since that means you won't end up in a situation that while the root
partition is nearly empty, the home directory is full.

man mkswap:
The old setup wastes most of this bitmap page, because
zero bits denote bad blocks or blocks past the end of the
swap space, and a simple integer suffices to indicate the
size of the swap space, while the bad blocks, if any, can
simply be listed. Nobody wants to use a swap space with
hundreds of bad blocks. (I would not even use a swap space
with 1 bad block.) In the new style swap area this is
precisely what is done. The maximum useful size of a swap
area now depends on the architecture. It is roughly 2GiB
on i386, PPC, m68k, ARM, 1GiB on sparc, 512MiB on mips,
128GiB on alpha and 3TiB on sparc64.
