How over engineered are receivers?

Is your insurance paid up? If the company reads this, and you had an accident because you ighnored safety ratings, do they cover it anyway?

Agree, but 'we' are in the minority here and most other forums when
it comes to 'specifications', 'ratings', 'limits', etc

As a retired computer R&D (labs for 11 years) and ex designer of industrial
stuff...know well the specifications our department, design team and
each individual signed for on each project

That was 'our' specification to design to...then the product team's
tech writers wrote up the published specification of our end product

Tech Writers were only one component of the team and really the summation
of all the design, testing, re-design, re-testing and finally certification
testing in house, then external certification at whichever agencies
(note plural) and of course the 'sometimes' re-design and re-certification
testing at those agencies

All that the OP is referring to is also known as 'design margin' at
the engineering/designer level. Outside it is normally known as 'safety margin'

Because there is an entity called "Mr Murphy" out there that crosses
many folks path 'some day' and many times often. Most folks think that
only happens to the other guy...

As for the 'sure you can' and 'have been for decades or thousands of
miles with no problems'...yes, but they are both lucky and still lucky
to have design margins left for whatever they are doing

My 1980 C10 Silverado's frame is still bent from the time I towed a
utility trailer from The SF Bayarea down to S Ca wind park to do
insurance work on busted windgenerators. Borrowed that C10 from dad
as it was his grocery store truck and I was a partner in a small startup
with no money

It did well and turned out that trailer was north of 14,000 pounds.
Also, that C10 long bed also had tools and metal stuff that must have
had the C10 weigh over 7,000 lbs (think really over 8K) when it's
GVWR was and still is 6,200 pounds

That would be a total of around 21,000 pounds for a 6,200 pound GVWR
'heavy half ton' truck...the frame is still bent from that trip

OBTW...this is a good thread on this topic of 'margin' and those using
all to over and those advising to do so with no ill effects...
