I do one step further and just don't use rm much at all. If I have a terminal open, it's probably because I got it from the right click menu in the file manager, and I can just click over probably faster than I could rm, and I don't really care to practice for hours to maybe get fast enough to save a few seconds. If I were to alias rm to something safer, I would probably get used to it, and over time start being less careful on the rare occasions I do use it. Then I'd SSH into some system that didn't have the alias, and screw myself over. rm should ideally have trashed stuff instead from the start, but since it doesn't, I think it's best to forevermore treat it as a dangerous command, unless all major distros switch.
