In particular, if I want to remove _exactly_ one package, I will always
use rpm and not yum.

Yum descends the packagae dependency tree and offers to also remove the
package that require the package I asked to remove. Easy to do damage
that way.

Rpm also descends the dependency tree, but will refuse the remove of if
another package depends on the one I asked to remove. Safer!

So Adalbert's "rpm -e preload" advice is good advice.

It happens that nothing depends on preload (I know this because I
routinely remove it from systems because it modifies binaries and that
sets off annoying alerts in our integrity monitoring software).

  yum is recommended because is makes a lot of common tasks much easier
  rpm is fine though, provided you are ok with its limitations;
    as described above - sometimes I want those limitations

The package state is kept entirely in the rpm database - it is safe, as
far as the database integrity goes, to mix use of rpm and yum as suits
your needs.
