Really not keen on the whole practice to be honest as there is absolutely zero imposed load on the tractor drawbar , no weight being carried by the tractor.
The "dolly is technically a trailer in its own right as it can be towed independently.
When coupled to the trailer the trailer then " technically" becomes a second trailer ( like towing two silage trailers) .
.
Your first point I quoted isn’t really true, you obviously have little experience using one with the correct design. The position of the fifth wheel according to the axle of dolly can be used to put a fair weight on the draw bar.
The dolly is only a trailer in its own right if it can be detached without the use of tools I believe. So that aspect can be overcome.
