Isn't this redundant? I always thought that "Enhances" is just the
reverse of "Suggests" ("A enhances B  <=> B suggests A").
The disadvantage of "Enhances" would be that it would need to know which
packages there are -- so every time a new data package is added, we
would need to update the updater package.

This would raise privacy concerns, since recommended packages are
installed by default, and this one would connect to some .mil domain
servers. Why not "suggests"?

Formats, download processes and further processing are data dependent
(and therefore part of the casacore-data-XXX package). The autoupdater
would just execute the update scripts that need to be provided by the
individual packages.
