1 - Maybe because images variations are created on-the-fly when you use them in a given template and the template is displayed? It sure would save a lot of space and processing time compared to "create all variations immediately for all images"...
2 - usage of image aliases is not tied to classes, but rather to templates

As all aliases are created at the time we upload an image with the online editor, I was amazed not seeing all aliases in the storage directory after uploading an image from an image dataype.
I just tested the on-the-fly image creation and, of course, it works perfectly.
