I agree this a bad default. I haven't had a chance to investigate much,
but it seems like the place we can control this is by setting
mm-inline-media-tests. IIUC, the third element of the alist element is a
function to test if the part should be inlined. By default this is
#'identity, which unconditionally inlines zip archives.
