Storing keyword info implies a catalog. If your catalog gets corrupt how will you differentiate your photos? If you give photos to others how will they know, which is which? I personally give all the images in a particular folder the same name with a number appended. For instance, in the folder, "2014-04-22 Washington DC - Air & Space" all the images would be in the format "14-04-22 Washington DC - Air and Space 1.cr2. Catalog or no catalog, search terms or no search terms, keywords or no keywords, old software a change in software, or no software at all, I will always know what the photos in that folder represent. Even if a photo is later stored in a different folder, I'll still know what it repesents. In my opinion after storing close to 35,000 raw images, not have a consistent naming system is a risk I'm not willing to take. Even just using a computers file manager will allow me to find and manage images.
