A frame material is just a material. the framebuilder has to consider the goals of the bike and the types of riders who will sit on top of it, and can use whatever material they're most experienced with to meet those goals. A bike that isn't built to handle a heavier rider can feel flexy and crappy for that rider and have reduced life expectancy, while a bike with a higher weight capacity can feel dead or harsh for a lighter rider. mass market bikes tend to be made with high weight limits, so designers use a variety of techniques to accommodate lighter riders.
The really nice steel bikes of yesteryear were designed with lightweight as the highest priority, and will be ropey under a heavier or more powerful rider. Like pic related, which is not at its best under my fat ass. Then as things transitioned over to aluminum, the stiffness wars began. Those were mostly over though, and some semblance of sanity was returning, and then disk brakes came along and required frames to be stiff and strong as fuck, so the cope is wide tires, microsuspension, and other stuff.
tldr, aluminum, ti, and carbon are as good for heavy riders as steel, sometimes better.
