Yes.  A basic element of clicking a link to save it is giving a
reasonable default filename.

On systems where the file type is determined by the extension
(Windows), it's also critical that the browser know what a reasonable
default extension is, including for proprietary file types not known
to the browser.  It's no good to have to tell users "if you're in
Windows, be sure to save this file with the following extension, since
browsers give us no way of making this happen automatically".
