As far as Content-Disposition already allows us to do this, yes.

Note that this doesn't allow bypassing the "open/save" dialog you see in
most browsers.  Content-Disposition: attachment asks the browser to show
that dialog, when otherwise it may have displayed the content directly,
without asking.  (Browsers generally don't have a "show this file in the
browser, even though it's C-D: attachment" option on that dialog--they
should, but that's a separate issue.)

 Better yet, File API could have an API for writing blobs to files.

FileWriter exists (don't think anyone's implemented it yet).  It's an
important API, but covers a different set of use cases.  <a download> allows
creating a download link to any URL (not just blobs) that behave like a
normal link, including things like the browser's standard context menu
items.  FileWriter doesn't do this.
