No. I would say ifpdf.sty, which tests for existance and value of
\pdfoutput, is the reference implementation for that. A informal survey
on my TEMXF tree revealed that most packages do something like this
(graphics.cfg, color.cfg, typearea.sty, ...). The only exceptions I
found where geometry and microtype. The latter does a complicated test
for \pdftexversion, which does not cause any problems here.

I think this is geometry's fault. And as long as Martin does not oppose
to you using the \pdf... primitives, I think it is best to use the same
