Re: Supporting extra parameters on the Intent object

I agree that having some such mechanism is essential.  I've been
experimenting with some real-world scenarios using the pick intent and it
seems clearly broken without a filename.  The proposed mechanism seems
reasonable to me.

My only concern is whether we really want to commit to all metadata for any
intent being strictly optional.  For the specific case of 'pick', I suspect
that services that don't have any reasonable filename will be much rarer
than clients that require a filename, and so I'd much rather put the burden
on services to fabricate the filename when necessary than on the clients
that need it (this can be non-trivial - eg. choosing an appropriate
extension to match the mime type of the data for compatibility with systems
like Windows).  It would be a shame for every client of pick to have to
maintain non-trivial filename generation code that only gets used in very
rare cases - or worse, services deciding they have to fabricate filenames
anyway due to a couple popular clients that don't properly do it
themselves.  Regardless, I think this API is OK for required metadata too -
as long as we're clear in the definition of each intent on what is required.
