I would far sooner just bet with a site that is licensed (there are a few of them around now), and has syndicated games from Microgaming or Betsoft that have their games tested and accredited by independent labs.
As for the license case, having a license doesnt mean that the site is actually fair but rather it is about the gray area of legal and illegal cases. Most sites around here is not licensed but that doesnt mean that they are not fair , the same thing applied to the site with license.
You are missing the ability to check your bet if you truly win or lose if there is no provably fair mechanism on the site. Having a shiny badge of either Microgaming or Betsoft in a gambling site is nothing but a gimmick either because no one truly knows whats behind the scene either (no offence but this is reality).
Standard would be the ability to verify your own lose . However most people dont know how to do it because it is quite "complicated" for them or they are too lazy to just copy-paste some seedhash, therefore people should just educate themselves about these things and accept these new industry standard
I think that at the end of the day you have to find a reputable casino because even the PF system has been gamed.
Or people can just simply educate themselves and check the provably fair thing by themselves but yeah this is too much hassle for some people , no doubt about it
