To me looks like they're using the one click installers from EBD, on mac is the same as Ned's result.
And since it seems just a copy & paste, and the're not even mirroring anything else apart from these packages,
And according to this:
they won't change anything, unless a project is abandoned, they just want the world to have everything available from their website...
So as Josh said, apparently no action needs to be taken (As long as EDB is still updating the one click installers, or SF has somewhere to download the installers from)
