Doing such "Real World" test to find unexpected side effects is a good
thing in a lot of cases. But you don't have to publish the results on
hundreds of pages if the results are as expected and hence uninteresting.

IOW: a lot of those phoronix articles that contain benchmarks could be
half as long or even shorter if you rip out the results that are of no
value and replace them by "No unexpected side effects could be found
when running tests foo, bar, baz, foobar, ...; We thus didn't publish
the results to not confuse and bore you".

Professional, printed computer magazine do things like that -- they have
to, because their space is quite limited. But that's not the case on the
web, where the methods to raise money make things even worse.
