Subject: last-modified document info?

Would it be a good, bad, or indifferent idea to allow clients to take
advantage of last-modified dates for documents when such information
exists and the document server can provide it?  Specifically, should
httpd be able to provide this information somehow, and/or should
last-modified become an optional field in the header of an HTML

Just random thoughts, based on the assumption that it sure would be
nice to be able to tell that document A was last modified in 1973...
