I see a lot of worries about road tubeless because the pressures are too high. I've used a whole bunch of different tires and had good luck with 28mm GP5000TLs, 28mm Goodyear Eagles and 32mm Panaracer Gravelking slicks on different bikes I use for road and mixed surface riding. I've had really bad luck with sidewall weeping and unreliable setups attempting to use Rene Herse tires tubeless , which sucks because those are probably my favorite tires.
One caveat: i run far lower pressures tubeless than I used to run tubed. F/R, I run 28s at 70/72psi and 32s at about 37/39psi. For reference, I weigh about 165 and I used to run 23s at 114psi when I used tubes. With tubeless, I really like running these lower pressures. I can feel noticeably more grip (especially on damp roads) and it's certainly much more comfortable. With the 28s, it's also not holding me back noticeably on 24+mph avg road rides with pulls at 30+.
Zipp, Giant and Enve are all currently pushing really wide hookless rims with 28mm-30mm tubeless tires at ~60psi as the future on the road. I personally see some merit in that. Anathema to traditionalists, though.
