I still have one bike running on 23s . It an old blue
Ribble winter bike running schwalbe Durano plus . I have looked at changing to 25s but the clearances just look too tight .
It doesn’t bother me as I used to ride to work all year round in all conditions for 30 years on various bikes none of which ever had a tyre wider than 25 and most had 23s. And I never once was uncomfortable or felt in added danger because of narrow tyres .
All my other road bikes are on 25s apart from one, where I am running 25 at the front and 28 on the rear. A set up I might change my best bike to going forward if I get the time ( my only outlier is my hybrid that’s on 32s) .
I am not against wider tyres for road bikes, it just personally when I have tried it I didn’t like how my bikes felt and behaved on the wider tyres.
