I think characterizing this as "nothing new but fresh vs saved" is
missing the key part of this: the point is that for the user, using a
file picker or a camera are two very different operations, and it's
likely that the developer would like to be able to influence which
operation will be presented to the user; see a related discussion in

That's what the Android implementation does, but as you note, that's not
what the specification states. The end goal would be to align with the
specification if doable, or to revisit it if not.

That's what the current spec says, as far as I can tell.
