Not necessarily, a lot of modern aluminum rims used on bikes intended for use as a touring bike are coming with just 32 spokes, and those rims are cracking at the spoke holes after just a few thousand miles, this also occurs with carbon fiber wheels on normal bikes.
Granted, cracks are usually associated with impact damage, poor manufacturing process and defects, but the less spokes there are the greater chance of cracks happening, and as the weight being carried goes up and spoke count goes down the risk multiplies.
Touring bikes today are being sold to make money for the manufacture, and they install cheap 32 spoke rims, if you use the bike for the way it was intended to be used, meaning touring with a load, those wheels will not last long, especially the rear wheel, you might get 4,000 miles before needing a new wheel. The construction of the rim means nothing, you need to have more spokes to spread the load out more across the rim.
I know about this first hand, and spoke to my bike mechanic about it, and read a lot about it on the internet. I have a 2023 Masi Giramondo 700 that came with 32 spoke rims that when I questioned the wisdom of using 32 spokes for a touring bike with the manufacture rep, he told me that the rim due to the way it is built will handle touring loads with no problems...2,000 miles later the rim had about dozen cracks at the holes, about 6 on one side and about 6 on the opposite side. I took the bike to a shop in town where I know the mechanic, and he said the rim failed due to too much load on the rim, and it was evident with the cracks being on opposing sides. This is a wheel set that was checked regularly by the bike shop to make sure the spokes were adjusted correctly and stayed adjusted, and they were assembled correctly from the factory. I might have been able to get a manufacture warranty on those wheels, but I would have had the same problem later, so I said screw it and bought a better back wheel.
The bike shop got me an Alex DC19 rim with 36 spokes instead of 32, and so far after 4,000 miles no cracks, and that rim is not an expensive rim, just like the Masi Brev M rim was not either, but that Alex rim is highly popular in the touring circles. I also threw out the rear Brev M hub and got a Shimano XT instead, can't really tell the difference in the way it rolls, but it is made a lot better than the Brev M and should last a very long time.
Even my bike mechanic said, including his own touring bike, that the wheels from the factory are trash, his cracked about the same mileage as mine did, except he replaced both wheels, I just replace the rear, the wheels look so similar no one would be able to discern a difference without getting real close. The front Brev M wheel I'm hoping should be fine for a long time, but I will have to keep a close eye on it for cracking, but I have a feeling the hub will fail before the rim.
Keep in mind that I'm running about 60 pounds of gear, food and water, along with 173 pounds of body weight that's 333 pounds being put onto my wheels, with the rear responsible for carrying about 70% of the weight.
