Surely, that the transaction operates in a predictable way? A temp table doesn't say, "I don't care about this data," it says, "I don't care about this data over the long haul." I've had lots of data go through temp tables that I really really wanted to get into some other place later, and it'd suck if the transaction failed half way through because it turns out there's nowhere to put the data I've just staged.
