dpkg does its own dependency checking, in addition to APT (the software, 
not the command), and will prevent any inconsistencies unless you use 
one of the --force switches.

In my opinion this is pretty safe ;)

APT, aptitude and others are more than just front ends to dpkg as they 
are also the ones working with your configured repositories.

'apt-get upgrade' is insufficient even on a stable system, e.g. due to 
the kernel package changing names, it's better to just use 'apt upgrade' 
(or 'aptitude safe-upgrade') instead.
