I've found it an issue too, especially in regards to braking.
Vehicles leaving the factory have to meet certain braking
distance standards, I doubt many conversions could meet them
in their GVWR-plus status.  At least with trucks there's a
chance you can beef up the brakes to the next-heavier version's
model, with cars there may not be much you can do.  That's
one of the reasons I would never stuff 1200lbs of floodeds
into a Rabbit or Escort, the chassis just was never meant to 
hold all that and still go down the road safely.  For those
EV owners that do and get away with it, it's due to safe 
driving habits and luck.  If there was a panic stop, forget it.

I put kevlar pads on my S-10 and that made the braking acceptable, 
but not anything like it was as an ICE with stock brakes.  It takes 
a solid honk on the pedal to get the tires anywhere near lockup.
My truck is at GVWR with no one in it.

It's pretty safe to say that most "mini-trucks" are just cars
with a cargo space.  I've got the same axle and suspension I'm
sure GM stuck in some of it's passenger cars.  Augmenting
the springs, adding sway bars, beefing up the brakes, etc
are pretty much mandatory if you expect the vehicle to handle
and brake safely with ~1000lbs of permanent extra payload.
If you proposed hauling around 1000lbs of cement in a stock
ICE Escort you'd be considered crazy, but for some reason if
you change the cement to batteries it somehow becomes OK. 
You could probably exceed GVWR by a significant percentage and
still not "break" anything, but I wouldn't want to be in front
of you.  There are also issues of accelerated wear, I only
get half as many miles on a set of tires and brakes as I used to.
I'm sure the bearings are taking a pounding too, and the springs
will fatigue and sag quicker.  It all takes it's toll...
