yup.. it does make it more manageable per se
but it does allow you the luxury of fixing the system if ti goes bonkers
by having / be 128MB or 256MB instead of lots-n-lots of disk that has
to be clean before it can boot itself

the simplest install ... ( relatively sane way )
<swap> partition of some size
<rest of disk>
-- no other partitions --
-- why bother w/ partitions -- if one wants it simple
-- and this 2 partition scheme usually isntall itself by
default(?) so no typing/thinking is needed ??

and getting back to making things messy:
/boot is NOT needed, unless the "kernel" is about the 1024 cylinder
boundry
- a left over artifact like swap == 2x real memory
( if one has 4GB of memory, in a large PC, does that mean
( we need 8GB of swap ?? ... nah.. not many apps need that
( much memory other that oracle and cae/cad simulations
( and bunch of special apps
and if you did have /boot ... how many 1MB sized kernels
does that /boot partition hold ???
1GB /boot implies about 1,000 kernels +/- :-)
( assuming you dont put anything else there )
if one is wondering about /boot ... it's more important toponder
the reasons for /tmp as a separate partition
