I think this is a much bigger deal than many give credit to; it does seem that a lot of people on WW don't ride much, or at all, in the wet - I'm certain that there's a big, and rapidly increasing, pool of riders who do ride in poor conditions and are spending more hours doing it as well. That on its own switches so many people to disc when they think about getting a new bike - properly done it's just a better system in the poor conditions, if you ride much. My rim brake setups do stop me well in most wet conditions, but the cost is rapid pad and rim wear. Pads okay, but expensive rims disappearing is big irritation.
Yes, there are improvements still needed to disc brake setups, on average [I hate the howling in the wet, and even Swissstop RS pads haven't stopped it completely for me].
For those that almost always ride in dry conditions, rim brakes can do a fantastic job. (as long as you can fit the rims and tires of your choice!)
Yes; you'd think we could all agree on that; it'll never happen!
