Honest question: Is there a good reason for this?

Rails provides a unique name to each version of the precompiled assets. If the file name is the same it's still the same file, regardless of the last modified date. There are many reasons why the Last-Modified date may differ. Removing it would completely eliminate the validation requests, relying on rails to simply provide a newly-named file when the asset changes. What am I missing?
