Mmm.

It wasn't designed to unify, but to cherry-pick the parts most used by
the "less sophisticated" (for want of a better term) user. This
explains the defaults chosen for it. It may also evolve with time in
a way that might make it hazardous for script users, particularly if
they don't keep up with the man pages.

Wisely, the OP quoted the precise commands they used, something that
all too often doesn't happen. The confusion over command/actions arose
later in the thread for no good reason. That's not the fault of apt
or apt-get.

Their aim is to preserve their interface across upgrades, so that scripts
using them (as recommended) don't require incessant modification.
