...Shimano specifically says the chainwheel/sprocket tooth
ration should be between 2.0 and 2.1.

I have never seen this spec for Nexus hubs. I suspect this is related
to the Smover automatic transmission system, not to any limitation of
the Nexus hub itself.

Smover isn't yet available on this side of The Pond, so I have no
experience with this, but as far as the hub itself is concerned,
there's no reason for Shimano or anyone else to object to a high gear
ratio. It's only chain ratios that overstress hubs.

My own Nexus 8 bikes are:

(I was running 52/18 when I was using that wheel on my Picchio tandem
for a couple of weeks.)

Just noting it.

It may sound maudlin, but I unmarked it as read, just so it wouldn't go
away.
