Maybe it has something to do with compatibility? Maybe some exotic systems that
run into trouble with this 'kosher' approach?

Then again it just may have to do with Unix people's brain cells being
hard-wired to using pipes whenever they hear "sed", "grep", "awk" or similar.

Anyway, we're not talking about runtime performance of POV here, just some
installation thing that runs fast enough as it is.
