What part of what you quoted makes using a directional tire unsafe or undesirable to use as a spare tire?
The difference between the right or wrong direction is literally not getting “optimal” traction. Sort of like a brand new tire vs one that is 50% worn out. Hardly worth the consternation about using one as a spare tire.

What I would REALLY PREFER on my 11,800 lb. (~fully loaded) 24 ft. Class C are Mud/Snow tires that are so over-spec'd for my MH such that if I blow a rear tire in the dually set - I can drive aways without changing it in situations where it blows and it is inconvenient or unsafe to stop and change it!!
i.e. I had an outside dually Michelin M/S LT LRE blow once years ago on a hard surface 4-lane road with light traffic. I was only a few miles from a small town, so I slowed down to ~10 MPH and drove all the way into the town and had a gas station attendant change it. Of course the other Michelin tire within the dually set was drastically overloaded while I traveled on it. That tire went on as if it had never been overloaded and provided several more years of service.
In other words - another parameter to shoot for in choosing tires for the rear of a rear-dually Class C is ... "can 3 tires in the rear (when one is flat) safely carry you along for aways at low speed until it can be changed?" This is what I call having a "redundancy" tire arrangement in the rear of a dually chassis - and it takes very rugged tires back there that have a generous-as-possible weight carrying margin over what they normally carry day-in and day-out.
P.S. I keep 80 lbs. of pressure in the rear tires all the time. I've compensated for the previously stiff ride in the rear by installing variable rate shocks in the rear that function as "no shocks" on highway cracks and as "heavy duty" shocks on roadway curves and in side-winds.

Personally, I see no downside in having extra weight carrying capacity. In my opinion, they are less likely to blow. If one does go flat, the remaining one that is temporarily carrying the full load will be less likely to also blow.
Note: You should never intentionally overload your rear axle.
Safe travels!

No downside other than availability and price. Sure, if one needs the added capacity, great. But based on your last statement, that's not likely unless one is actually overloading the "real" axle capacities (aka the 10-11klb range) of the vehicle.
And if the extra capacity is needed, barring some obscure tire clearance issue on the RV, there are other options that are of similar or same capacity and not an obscure Euro tire size (albeit not as obscure as years past with the amount of Sprinter type vans running around.
Overkill is fine, it's one person's own money vs peace of mind I suppose. Just pointing out the (not obvious to everyone) differences and costs/challenges for little to no real world gain.

And to dispell another myth posted by BigToe, there is no harm in using directional tires backwards other than less than “optimal” traction that is provided by the design of the tread.

And why would one intentionally use tires (225-75-16C) that are far less popular and less available than all the applicable comparable tires that are commonplace and can be found at any tire shop virtually anywhere in North America?
