Currently my own view is that exposing a filesystem type API must be opt-in (as 
in new code has to be written to use it; old code isn't going to "just work"). 
As such a new attribute [value] such as multiple=fs could be required to make 
use of it, and could change the behavior of the input so that it doesn't build 
up a FileList, but instead sets .files to an object representing the picked 
directory if a directory is picked.
