Probably I should've put extra stress on the word "reuse".
The example quoted was trivial; if you replace the pipeline to have
say 5 processes, the advantage of not-reinventing the wheel becomes
more obvious.
I would call hand-crafting the pipe-setup an "overkill" when a very
good solution already exists to solve the problem. Yes, it may be
trivial to do; but not simpler than delegating to a shell.
