Never called rpm with --force AFAIR (and before someone goes to grep the apt
tree, like every time this comes up: yes grep finds a --force reference in the
sources but it's not used unless specified by the user), --nodeps was and still
is used because it *has* to do so as long as it doesn't use rpmlib. Rpm doesn't
support simultaneous install/upgrade/erasure operations within a single command
so apt has to "simulate" a complete transaction by doing separate runs of erase,
install and upgrade operations with --nodeps called. Also it already resolves
the package dependencies and install order by itself so why recalculate in rpm
-> calling rpm with --nodeps --noorder isn't anywhere near as bad as it sounds
*in this context*.
