Snark aside, why would I buy an Audi A3 when I already have a Honda? My truck is much more capable than your A3 and was probably much cheaper. Regarding safety, it's actually really safe because I only drive it when I need its hauling or towing capability.
That said, as a former A4 owner, towing 1000+kg with an A3 seems like a death wish to me.
Agree with you on the tow ratings though. It's a really good idea to have some healthy margin between the stated limit and the actual load, unless you're just going down the street.
Not only that, but in some applications the stated limit is irrelevant. Utility trailers aren't usually a big problem, but a lot of people mistakenly think they can tow a 7500lb RV with a half-ton truck just because the manufacturer says the tow rating is some ridiculous number like 11,300 lb.
But realistically, payload is what you hit first, especially a family towing a travel trailer. A very typical half-ton pickup will have around 1500 lbs of payload capacity [0]. This includes driver, passengers, cargo, everything but fuel. The authoritative number is particular to the truck and is given on a sticker on the door jamb. So if you have a trailer with a 7500 GVWR, you need to plan on around 1050 lbs on the tongue, which leaves you ~450 for everything else. Two adults could easily put you over. Add kids, dog, coolers, firewood for the campsite, etc, and suddenly a half-ton isn't looking like a good choice for a trailer this size (7500 GVWR is what a typical ~30 ft travel trailer is spec'd at).
There are other factors that also come into play, like wheelbase vs trailer length, but in general I think most people don't have much to worry about if they respect the payload rating on the truck. Many people ignore it (on purpose, or not) however. I've seen more than one F150 towing a 35 foot trailer. On anything other than flat, level highway with no crosswind and little traffic I think that would be dangerous.
[0] Technically Ford will sell you a particular F150 configuration with a 3270 payload, higher than many F250s, but IMO it's still not as comfortable towing as a bog standard F250. But if you don't tow very often the compromise may be worth it since the F150 is significantly more comfortable for daily driving.

I see what you mean now. I cannot imagine towing a 30+ft trailer with a half ton. I feel iffy pulling our 16ft TT with the T100. It's well within capacity, but I definitely feel the truck working. And yeah, flat ground is smooth sailing, but the first hill you hit and the pedal is down all the way and if I don't hit it just right I've got to tell the auto to shift to 2nd.
Probably could have gone one size up, but I'm honestly really happy with the T100.
