If people would simply move to a modern-PDF/X-4-based workflow, where transparency can be left live - this would all go away...

We have and you are correct...however, there is a lot of legacy hardware out there still in use that just doesn't understand transparency.

Not hardware but software. But both are relatively easily upgraded. You can't hold off forever.

We already have as I said earlier. There are still a lot of people using old rips, both hardware and software, that can't handle transparency. Drives me crazy when I see someone recommending a PDF-X1A but some people still need flattened files. Another issue is Fiery RIP's for digital copiers. Transparency is a problem for those still.
