The reason alias files no longer fit in 4KB is that each alias file contains a custom icon (so that Finder can display an icon for the alias without having to possibly mount a network volume just to get one from the application), and icons keep getting bigger. It isn't that new features are being added; it's that the old features take more disk space to match the increasing resolution of our monitors.
The extra space has absolutely nothing to do with QuickLook. QuickLook resolves the alias and gives you a quick look into the contents of the target file. If QuickLook can't resolve the alias, it shows you nothing informative. References to QuickLook in this thread are probably meant to be references to Finder's "Icon Preview" option, which amounts to a second custom icon derived from the contents of the file, as of the time the alias file was created.
