Considering that the system is going down anyway, why bother?  It's
sort of like requiring that programs free() all their memory before
calling exit(); nice to do for debugging purposes but usually just
slows you down.  I can also think of cases where you may still have
processes hanging around whose swapped-out VM size is greater than
physical RAM.

Having said that, it's still no excuse for a panic :)
