Of course there are exceptions for the super rare wood rimmed "balloon" tired racers. Continental 22mm tubulars are the sweet spot for my bikes and for clinchers -- GP4000s in 23mm. (If I ever wear out my 4000s I'll give the 5000s a try.)
I really don't care what any one else rides, but I'm happy looking stupid on all of my bikes. In the past 10 years the skinniest tire I've ridden is 32mm. Roads in rural Oregon can be rough, some aren't even paved, wider tires make riding on them much more comfortable, and safer. YMMV.
The issue on a lot of classic road racing bikes is there isn't
room for bigger han 25mm tires.
