Yup, "upgrade" has other limitations (on purpose), like never installing 
or removing packages, if the dependencies of a new package require such 
actions "upgrade" will just hold back such updates. So sticking to upgrade 
would limit possibilities of what can be done in updates a lot. So pretty 
much everybody (at least outside Debian :) uses dist-upgrade for all 
updates.
