That was probably me, but I really don't see it as an issue. You have to take the bikes off anyway, and pulling the pin and dropping the rack to the ground is a two minute operation. With rack and bikes on the front, the CAT scales show my tongue weight below 15% on my X19H, so not really a problem. The Arvika rack mounts are far enough back on the A-frame that only about 75% of the weight is going to the tongue, and 25% to the TT axle.
Note that the native Arvika type full installations are a bit cleaner; I went for this configuration so I can swap my rack back and forth between the TV and TT when we get to our destination so we can drive to a remote ride.
All solutions have trade offs. Packing the bikes inside is wear and tear, and some here tells the tale of the bike accidentally turning on the propane to the stove while travelling. Bike racks on the back bumper have the leverage effect and get a lot more whip back there. They also have to be unloaded and dropped/removed to drop the rear bunk.
A double receiver may shift the TT further back depending on how it mounts; that can further exacerbate weight distribution issues by moving the TW further behind the rear axle (if the load point is moved further back, you create a From the rear axle loading view, it is also probably worse than the A-frame mount as none of the bike/rack weight is borne by the TT. A front receiver for the TV can be a great solution if it can be fitted as it moves load forward to the front axle, and reduces the amount of weight that needs to be transferred forward by your WDH.
