There are only very very few people who will be able to cast a full
#3DT line. Indeed, the vast majority will never even get close to 65
feet. But there are plenty who can quite easily cast thirty feet of
#10 line on a #3 weight rod quite a long way.

There's your problem with generalizations, many three weights don't have the
taper to not get overpowered by 30' of #10 line, but without resorting to
name calling I would have to agree trying to cast 90' of 3wt is different
than trying to cast 30' of 10wt, regardless of the rod.

Furthermore, there is NOBODY who can cast a weighted #6 woolly bugger
60 feet, or even close to it, using a #3 weight line and a #3 weight
rod.

I'm not a particularly accomplished caster and I would take that bet.
Regardless I know several who could make that cast.

This involves double hauling the thirty foot head ( or however long
the matched piece happens to be), and shooting the backing. It is not
even particularly difficult.

The weight is the same, merely the length of the weight has changed.
This has no affect at all on the rod.

Disagree again, The weight of the line is but one factor. The length of the
aerolized line is but one component of the process, that's why people who
try to back cast with 30' of WF line often loose it because the
combination of rod load, line speed, and taper get all shot to hell when the
fatter "head" portion is dependent upon the skinnier running line to support
the flight path. There were specific rods made to aerolize line but they
tend to be softer action than the medium fast to fast action rods in vogue
on this side of the pond.
