What proportion of the total Sage tarball would be taken up by these upstream ones? I can imagine two versions of Sage's tarbal, one with and one without, so that it would still be possible to download the whole thing at once, but also possible to download the small one (with none of the upstream ones) and have the build system download those as needed, rather as happens with a git-based install. In the latter case it would even be possible to grab the upstream tarballs from an upstream website instead of sage's own (with a filename and checksum check to make sure that the correct version was used)? Of course the possibility to download everything at once and build online will always remain.
