I always look inside the fuse and epoxy or CA (sparingly) any parts that's lacking hot glue or what ever they use at these factories. I just got done stripping a Discontinued Great Planes .60 Fokker and one spar in the fuse was only glued at one end and not the other, it was just hanging and if I hadn't removed the covering I wouldn't had seen it! I always add a little epoxy around the servo tray, firewall and landing gear mounts if I can get in there with the glue. It gives it extra support for those terrible landings I like to do at times.
I haven't had a structual failure from a ARF yet, Thank God! I have faith that the factory uses enough glue in the wings and places I can't get at and I go from there. If it were me and I was too worried, then I would say " Screw it " and just buy the kits.
The benifits would be that I would know that everything was glued right, plus it would help the kit sales.
