Is that your legendary Centronics 36-pin SCSI?

As usual, you're speculating. Whether the author knew or did not know is not something you can discern, and what you describe is common knowledge — common knowledge which makes some of your earlier statements even more pointless.

I never said that there aren't 16-bit SCSI controllers on the Amiga. I'm just not lucky enough to own one, like the vast majority of Amiga owners who would consider using this solution.

If you've plugged a FAS216U into a Fastlane Z3 or Blizzard SCSI kit, do report your findings. I suppose your data bus magically widened at the same time.

Or rather, I suppose you're doing your usual thing: speculating, spreading misinformation and derailing.

Exactly. Again, I suppose this has been a big problem for you in your Amiga using life?

Even a humble WD33C3 controller can sometimes do up to 10MB second synchronous transfer, but sadly most A1200 Blizzard SCSI kits are limited to SCSI one speeds. Tough.
I would strongly urge SCSI card owners to pay no respect to your speculations and go on with their lives, asking someone knowledgeable like Daedalus in case they have questions about how wide their SCSI bus is or how to set it up.
