Yes, that would definitely be an idea. There was some discussion
yesterday evening about this on IRC with Yann E. Morin, and indeed one
of the idea that came up is to have something like
<pkg>_DOWNLOAD_TRANSIENT = YES, which would tell the download
infrastructure to refetch from upstream everytime the package is built
instead of using a locally available tarball.
