I concur, but isn't that independent from Romain's patch? Romain's
patch is about passing random additional options straight from the
package to the download helper. How would such custom options be passed
with your new scheme ? I guess we would pass first the downloader
wrapper options, then a "--" sign, and then the custom options passed
straight to the download tool. Do you see another way ?

Also, I'm tempted to say that Romain's patch can be merged as-is, since
switching to a different organization of the download helpers will no
affect the visible "API" exposed to packages.

What do you think?
