There are strong reasons for a seperat /tmp and /var partitions. Most
importantly because both are writable and written to.
/tmp should default to tmpfs and D-I should not create a partition for
it normaly. There could be recipies for a sperate /tmp partition but it
shouldn't be the default. I agree that people that need a seperate /tmp
partition will know that they do.
As for /var that should be a seperate partition. The default setup
should allow / to be mounted read-only even if that isn't the default.
Besides that it also reduces fragmentation and lessens the risk of
filesystem corruption on /. Overall it is a good idea and having it a
seperate partition is no burden for the normal user.

Imho the default should be /, /var and /home as LVM LVs and /tmp as
tmpfs. It is minimal but flexible.
