FWIW, I think expostion \luatexversion is the simplest, hence the best, solution.

I agree with you that the runtime detection should belong to the format.
However, given that things running on top of LaTeX2e will probably need to
detect the engine themselves a least for some time, it's best to provide and
document a simple and reliable detection mechanism.

My primary concern here is to try and avoid reproducing the problems with wrong
\pdfoutput hacks as Ulrike said.
