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

 But we could certainly add some way to enable creating an <input>

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

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.)
