I'd suggest <input type=directory>, which causes a directory picker to be
shown, doesn't populate .files at all, and adds an API entry point to
retrieve a filesystem.  If somebody suggests an implementable way to expose
UI that doesn't need to separate files and directories then we may want
something else, but that doesn't seem likely to me.

directory.  So, something like type=filesystem might be a better name.)

The downside with this approach is that it doesn't work well on systems
that doesn't have a filesystem in the traditional sense though. Such as
most mobile platforms.

I'd rather extend <input type=file multiple> such that platforms that have
directories can expose those, and ones that don't just expose files.

And on platforms that have combined file-or-directory pickers can render a
single button, and platforms that use separate Widgets can render two

Then we of course need to deal with pages that want to do their own
