It was good enough to put a bunch of crap on one line that wasn't spaced
properly, and was otherwise completely unreadable. At the end, your
prompt would be *somewhere* on the terminal... When has it ever been
useful or acceptable to not generate newlines? Seriously, how could you
possibly make sense of this output (which you yourself suggest):
rpm -qa --qf "%{NAME} %{VERSION}-%{RELEASE} %{ARCH}"
It was never "good enough" before.

So would I... Disappointed that anyone who wrote a program that ran for
two weeks would a) write output to a terminal: the place it's MOST
LIKELY to be lost entirely, and b) didn't format the output to be
readable.
I'd probably be suspect enough to never trust the results enough to even
run the program a second time. "rm -rf piss-poor-program" :-)
