When I use #2, I'm just setting the filename. "inline" is only there
because it has to be; there's no way of saying "Content-Disposition: don't
care; filename=foo". "inline" is the default.
I think @download should be able to force a download regardless of whether
a C-D header exists: treat the default C-D as "inline", and don't change
behavior just because a header states the default.
I don't know if it should be able to override a C-D filename parameter. I
can't think of any case where this is useful, so if it helps get this
feature available cross-origin then that's fine. (Half of the point of
this feature is to allow adjusting filenames on external content servers
which you don't have much control over.)
