Sure we can; we can always add to that API, such as adding a
getFileSystem() method. A different @type may be better anyway, though.
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.

But we could certainly add some way to enable creating an <input>
which exposes files and directories in the DOM, rather than just
files. Doing that will depend on coming up with a filesystem proposal
which all parties actually agree on implementing, so far we don't have
such a proposal.
Unless we think it won't ever happen, it'd be better to keep working
towards that than to rush things and implement greedy recursion.
It also requires an actual proposal for what such an <input> would
look like. I.e. would it be an <input type=file directory>? Or <input
type=file multiple> with some sort of API call saying that flattening
directories into files aren't needed? Or <input
type=filesanddirectories>?
It's probably not worth worrying about this part too much until we have a
filesystem API for it to enable. Any of these seem fine (though I'd lean
away from an API call), or maybe <input type=file multiple=fs>, which would
cause it to fall back on the current (files only, non-recursive FileList)
behavior on browsers that don't support it.
(I don't think "flattening directories into files" is something that should
ever happen in the first place, but if it does we'd definitely need to make
sure it doesn't happen in this mode.)
