I can list a tons of commands that "ruins your system" ...
While I might understand why use "yum remove kernel" (to remove
everything but the running kernel) the other commands do not make
sense.

dd if=/dev/zero of=/dev/sda also "ruins the system" ... -> strawman

Or maybe there is a bug (memory leak)? Did you file one?

Well sure doing things properly costs more time initially,  but it
will pay off later.
Anyway the cli interface of yum was never considered to be an api, so
scripts that use it
as if it where might break anytime. Even worse are scripts that try to
parse output that is
not guaranteed to be stable nor machine readable.
